Transmit diversity and expansion in space for an OFDM-based communication systems with multiple antennas

摘要

1. A method of transmitting data from a transmitting entity to a receiving entity in a wireless multi-antenna communication using Orthogonal Frequency Division Multiplexing (OFDM), soderzhaschiyobrabotku data packet to obtain a block of data symbols, demultiplexing pilot symbols and the block of data symbols into a plurality of subbands to obtain, for the data packet, a plurality of sequences of pilot symbols and data for a plurality of subbands; and performing spatial processing on the sequence of pilot symbols and the data for each subband with at least one steering vector selected for the subband, the spatial processing randomizing a plurality of active channels of a single-input single-output (SISO), corresponding to the plural symbol sequences pilot and data sent by poddiapazonov.2 set. A method according to claim 1, wherein the sequence of pilot symbols and the data for each subband is spatially processed with one steering vector selected for poddiapazona.3. A method according to claim 2, wherein the plurality of subbands is used for a plurality of different vectors upravleniya.4. A method according to claim 2, wherein the one steering vector used for spatial processing for each subband is unknown to the receiving obektu.5. A method according to claim 1, wherein the sequence of pilot symbols and the data for each subband is spatially processed with at least two steering vectors selected for poddiapazona.6. FPIC
