The method and apparatus for combining signals from a plurality of spaced SOURCES

摘要

1. A process for adding signals from a plurality of spaced sources, comprising the steps of: perform alignment and addition based on the optimal addition (MRC) to signals from the spaced receiver antennas; ! perform alignment and summation based on MRC for repetition diversity signals; and! performing equalization on MRC-based addition to spaced with overlapping signals! said alignment and MRC-based composition for signals spaced receiver antennas, alignment and MRC-based composition for diversity repetition signals, and alignment and MRC-based addition to spaced with overlapping signals operate each separately. ! 2. The method of claim 1, wherein: alignment and MRC-based composition for repetition diversity is performed after signals on MRC-based equalization and for adding signals from the receiver antenna diversity; and! alignment and MRC-based composition for duplication diversity is performed after signal equalization and addition based on MRC for repetition diversity signals. ! 3. The method of claim 1 wherein the alignment and MRC-based composition for the signals with the receiver antenna diversity is performed as! ! where i - Index of OFDMA symbols, where - a communication channel index, wherein n - the index of the fast Fourier transform, where N c indicates the number of receive antennas, where R sdr () indicates the result derandomizing subcarriers and wherein H p () indicates the result of channel estimation. ! 4. The method of claim 1 wherein the alignment and MRC-based composition for repetition diversity signals operate as where where where k - index number of subcarriers per slot, wherein s - distributed
