Abstract:
1. A method for finding cyclic shift diversity (CSD) using autocorrelations, the method comprising: receiving, with a receiver, an orthogonal frequency-division multiplexing (OFDM) signal; computing, with at least one processor, a delay-based autocorrelation of the OFDM signal to form a delay-based autocorrelation result; computing, with the at least one processor, a cyclic shift-based autocorrelation of the OFDM signal to form a cyclic shift-based autocorrelation result; comparing, with the at least one processor, the delay-based autocorrelation result to the cyclic shift-based autocorrelation result to form a comparison; and determining, with the at least one processor, a CSD mode based on the comparison.
