ABSTRACT:
A wireless communications system including an antenna configured to receive a sequence of symbols through a channel, in which the sequence of symbols comprise bits of user data that have been previously mapped to the sequence of symbols. The wireless communications system further includes a demodulator configured to generate a sequence of demodulated symbols by multiplying the sequence of symbols by a conjugate of a channel response of the channel; a demultiplexer configured to generate an in-phase component and a quadrature component of each demodulated symbol in the sequence of demodulated symbols; a slicer configured to, for each demodulated symbol, generate a decoded symbol by performing a hard decision based on the in-phase component and the quadrature component of the demodulated symbol; and a bit mapping module configured to determine the bits of user data associated with each decoded symbol.
