Abstract:
1. A multiple-input multiple-output code division multiple access (MIMO-CDMA) wireless communication equipment, comprising a transmitter and a receiver, wherein the transmitter comprises: an encoder for receiving a plurality of transmission data and encoding them; a quadrature phase-shift keying (QPSK) unit for conducting QPSK modulating to an output of the encoder; a space-time block coding (STBC) unit for conducting space-time coding to an output of the QPSK unit; a preamble code spreading unit for generating a plurality of preamble codes; a plurality of data frame generating modules for generating a data frame based on the outputs of the STBC unit and the preamble code spreading unit, a pilot code and a cyclic prefix; and a plurality of transmitting antennas coupled to the corresponding data frame generating modules respectively, wherein each of the data frame generating modules sends the generated data frame to the receiver via a corresponding transmitting antenna.
