Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Broadband Radio Access Networks (BRAN). The pres

20、ent document describes the physical layer specifications for High PERformance Radio Metropolitan Area Network (HiperMAN). Separate ETSI documents provide details on the system overview, Data Link Control (DLC) layer, Convergence Layers (CL) and conformance testing requirements for HiperMAN. With per

21、mission of IEEE(on file as BRAN43d016), portions of the present document are excerpted from IEEE Standards 2 and 3. ETSI ETSI TS 102 177 V1.5.1 (2010-05)61 Scope The present document specifies the HiperMAN air interface with the specification layer 1 (physical layer), which can be used to provide Fi

22、xed applications, in frequencies below 11 GHz, and Nomadic and converged Fixed-Nomadic applications, in frequencies below 6 GHz. The present document follows the ISO-OSI model. HiperMAN is confined only to the radio subsystems consisting of the Physical (PHY) layer and the DLC layer - which are both

23、 core network independent - and the core network specific convergence sub-layer. For managing radio resources and connection control, the Data Link Control (DLC) protocol is applied, which uses the transmission services of the DLC layer. Convergence layers above the DLC layer handle the inter-workin

24、g with layers at the top of the radio sub-system. The scope of the present document is as follows: It gives a description of the physical layer for HiperMAN systems. It specifies the transmission scheme in order to allow interoperability between equipment developed by different manufacturers. This i

25、s achieved by describing scrambling, channel coding, modulation, framing, control mechanisms, and power control to assist in radio resource management. It does cover the receiver and transmitter performance requirements which are specific for HiperMAN systems. Some information clauses and annexes de

26、scribe parameters and system models to assist in preparing conformance, interoperability and coexistence specifications. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

43、Xclusive OR 4 HiperMAN OFDM PHY 4.1 OFDM symbol description An OFDM waveform is created by applying an Inverse-Fourier-transform to the source data. The resultant time duration is referred to as the useful symbol time bT . A copy of the last gT s of the useful symbol period, termed Cyclic Prefix (CP

44、), is prepended to enable the collection of multipath at the receiver, without loss of orthogonality between the tones. The resulting waveform is termed the symbol time sT . Figure 1 illustrates this structure. g T b T s T Copy samples Figure 1: OFDM symbol time structure The transmitter energy incr

45、eases with the length of the CP while the receiver energy remains the same (the CP is discarded), so there is a )10log(/)/(1(log10gbgTTT + dB loss in SNR. Using the CP, the samples required for performing the FFT at the receiver can be taken anywhere over the length of the extended symbol. This prov

46、ides multipath immunity as well as a tolerance for symbol time synchronization errors. On system initialization, the Base Station (BS) CP fraction (bgTT / ) shall be set to a specific value for use on the Downlink (DL). Once the BS is operational the CP value shall not be changed. On initialization,

47、 the Subscriber Station (SS) shall search all possible values of CP until it finds the CP being used by the serving BS. The SS shall use the same CP values determined in DL for the UL. Changing the CP value parameter at the BS through (re)initialization forces all SS registered on that BS to re-sync

48、hronize. In the frequency domain, each OFDM symbol is comprised of multiple carriers (see figure 2), which belong to one of three types: Data carriers - for data transmission. Pilot carriers - for channel estimation and other purposes. Null carriers - for guard bands and the DC carrier. ETSI ETSI TS
