This work considers a high rate, multiple input multiple output (MIMO) system using multiple codes, as well as channel coding and space time (ST) coding. The transmitter consists of a channel encoder followed by parallel Linear Dispersion Codes (LDC) ST encoders using different spreading codes. The iterative receiver consists of a soft input and soft output (SISO) demodulator, followed by a SISO decoder. The demodulator is based on the well known linear multiuser detector. Simulation results in realistic frequency selective Third Generation Partnership Project test cases reveal good performance even for high rate HSDPA services.
