Abstract
Systems, apparatus and methods for determining a cyclic shift diversity (CSD) mode are presented. Examples use a channel impulse response (CIR) to determine a current CSD mode. Specifically, a channel impulse response from an orthogonal frequency-division multiplexing (OFDM) symbol, which forms CIR samples. The CIR samples are examined to find a local maxima. A current CSD mode may be selected based on the local maxima found in the CIR samples.
