Abstract:
1. A method comprising the steps of: receiving a received signal from a wireless communication channel, wherein the received signal represents a channel-affected version of a selected signal that was transmitted by a transmitter, and wherein the selected signal represents a signal selected by the transmitter from a plurality of candidate signals, and wherein the received signal includes a combination of a phase shifted input data signal with a synchronization/pilot sequence; determining an estimate of a selective mapping (SLM) index, which identifies the synchronization/pilot sequence from a plurality of synchronization/pilot sequences; applying corrections to the received signal based on estimated channel perturbations within the received signal, which estimated channel perturbations are determined based on the estimate of the SLM index, to produce an equalized combined signal; and producing an output data symbol from the equalized combined signal.
