Abstract

This work considers a high rate, multiple input multiple output (MIMO) systems 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 detector. Simulation results in realistic frequency selective third generation partnership project test cases reveal good performance even for high rate HSDPA services.
