15、13 All rights reserved 1Space data and information transfer systems Flexible advanced coding and modulation scheme for high rate telemetry applications 1 Scope This International Standard defines an efficient and comprehensive coding and modulation solution able to support a wide range of spectral e

16、fficiency values and data rates. The main target is given by high data rate telemetry applications, i.e. Earth Exploration Satellite Service (EESS) telemetry payload, where the increase of the system throughput by means of advanced adaptive techniques is deemed essential in order to fulfil the requi

17、rements imposed by future missions. This International Standard presents a turbo-like coding/modulation scheme based on one possible realization of a Serial Concatenated Convolutional Code (SCCC). This scheme makes use of a set of a large variety of modulation techniques (including QPSK, 8PSK, 16APS

18、K, 32APSK, and 64APSK) and a wide range of coding rates. The number of different modulation schemes available, combined with a properly selected coding rate, allows the overall system to make efficient use of the available bandwidth, adapting itself to the variable conditions of the link. The propos

19、ed scheme can implement Variable Coding and Modulation (VCM) mode, which varies the transmission scheme to the channel conditions following a predetermined schedule (for example, as a function of the elevation angle). When a channel is available to provide feedback (e.g. via Telecommand), the transm

20、ission scheme can be dynamically adjusted using the Adaptive Coding and Modulation (ACM) mode. The proposed coding scheme is easily adapted to any of the available modulation formats thanks to the pragmatic approach adopted: the outputs of the binary encoders are mapped to the considered modulation

21、scheme, after being interleaved. In other words, a bit-interleaved coded modulation scheme is proposed (reference F1). The use of SCCC is intended mainly for high data rate applications. The Forward Error Correction (FEC) scheme is based on the concatenation of two simple four-state encoder structur

22、es. The SCCC scheme implies a Physical Layer frame of constant length, with pilots inserted in fixed positions. This architecture simplifies the synchronization procedure, thus further allowing fast and efficient acquisition at very high rates for the receiver. This International Standard describes

23、a technique incorporating multiple modulation formats paired with a flexible coding and synchronization method in a tightly integrated fashion. In particular, this International Standard provides a series of recommended formats where each format pairs a modulation technique with a tailored implement

24、ation of the coding and synchronization method. However, where these modulations and/or codes are recommended in other CCSDS documents, this International Standard does not limit the choice of modulations and/or codes consistent with those recommendations. The scope and field of application are furt

25、hermore detailed in subclause 1.3 of the enclosed CCSDS publication. 2 Requirements Requirements are the technical recommendations made in the following publication (reproduced on the following pages), which is adopted as an International Standard: CCSDS 131.2-B-1, March 2012, Flexible advanced codi

34、S CCSDS 131.2-B-1 Page ii March 2012 STATEMENT OF INTENT The Consultative Committee for Space Data Systems (CCSDS) is an organization officially established by the management of its members. The Committee meets periodically to address data systems problems that are common to all participants, and to

35、 formulate sound technical solutions to these problems. Inasmuch as participation in the CCSDS is completely voluntary, the results of Committee actions are termed Recommended Standards and are not considered binding on any Agency. This Recommended Standard is issued by, and represents the consensus

36、 of, the CCSDS members. Endorsement of this Recommendation is entirely voluntary. Endorsement, however, indicates the following understandings: o Whenever a member establishes a CCSDS-related standard, this standard will be in accord with the relevant Recommended Standard. Establishing such a standa

37、rd does not preclude other provisions which a member may develop. o Whenever a member establishes a CCSDS-related standard, that member will provide other CCSDS members with the following information: - The standard itself. - The anticipated date of initial operational capability. - The anticipated

38、duration of operational service. o Specific service arrangements shall be made via memoranda of agreement. Neither this Recommended Standard nor any ensuing standard is a substitute for a memorandum of agreement. No later than three years from its date of issuance, this Recommended Standard will be

39、reviewed by the CCSDS to determine whether it should: (1) remain in effect without change; (2) be changed to reflect the impact of new technologies, new requirements, or new directions; or (3) be retired or canceled. In those instances when a new version of a Recommended Standard is issued, existing

40、 CCSDS-related member standards and implementations are not negated or deemed to be non-CCSDS compatible. It is the responsibility of each member to determine when such standards or implementations are to be modified. Each member is, however, strongly encouraged to direct planning for its new standa

41、rds and implementations towards the later version of the Recommended Standard.

42、RD This document describes a Serially Concatenated Convolutional turbo Coding (SCCC) scheme for telemetry applications. The flexibility, performance, and proper architecture of the proposed coding scheme together with a new frame structure make the scheme suitable for achieving a significantly high

43、spectral and power efficiency while maintaining compatibility with the existing data layer protocols. The proposed coding scheme and its associated frame structure are specifically designed to support reconfiguration of the downlink channel (variable or adaptive coding and modulation) and to provide

44、 means for reliable synchronization at the Physical Layer and the Data Link Layer. Through the process of normal evolution, it is expected that expansion, deletion, or modification of this document may occur. This Recommended Standard is therefore subject to CCSDS document management and change cont

45、rol procedures, which are defined in the Procedures Manual for the Consultative Committee for Space Data Systems.
