Abstract:
1. An apparatus of transmitter for multiple input/multiple output multicarrier-code division multiple access (MIMO MC-CDMA) systems, comprising: a K-input/K*M-output modified orthogonal transmit diversity (MOTD) encoder where K and M are integers, K≧1 M≧1 with at least one data stream as its input and at least one symbol stream as its output; a combiner connected to the K-input/K*M-output MOTD encoder, which is with at least one combined symbol stream as its output; at least one code spreader, each of which is connected to the combiner and spreads the combined symbol stream to generate a symbol stream as its output; at least one multi-carrier modulator, each of which is connected to the at least one code spreader; and at least one set of transmitting antennas used for radiating the at least one RF signal stream, each set of which is up converted from the output of the at least one multi-carrier modulator.
