Abstract
Improved space-time coding for multiple-input and multiple-output orthogona l frequency division multiplexing is studied for wireless systems using QPS K modulation for four transmit and four receive antennas. A 256-state code is shown to perform within 3 dB of outage capacity (and within 2 dB with pe rfect channel estimation), which is better than any other published result without using iterative decoding.
