Patent ID: 7961819

Claim:
A wireless communications system comprising: an antenna configured to receive a sequence of symbols through a channel, wherein (i) the sequence of symbols comprise bits of user data, and (ii) the bits of user data are mapped to the sequence of symbols prior to being received by the antenna; 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 of the demodulated symbols; a slicer configured to, for each respective one of the demodulated symbols, generate a decoded symbol by performing a hard decision based on the in-phase component and the quadrature component of the respective one of the demodulated symbols; and a bit mapping module configured to determine which of the bits of user data are associated with each of the decoded symbols.
