Abstract

It has recently been shown that the capacity for multi-antenna dispersive radio channels is considerably higher than single receive and transmit antenna systems. In this article we demonstrate that high data rates can be achieved at low power levels for systems where the number of transmit, antennas is typically larger than the number of receive antennas. We use bit-interleaved coded modulation, iterative decoding, and OFDM system building blocks for a flexible class of space-time coding systems where it is easy to change convolutional code rate, constellation size, and the number of transmit and receive antennas for designing systems with a wide range of capabilities. The coding is typically done in the time, frequency, and space domains. The gain can be used for either high data rates and/or lower power levels. Applications can be found in future wireless LANs and/or B3G and 4G wireless cellular systems.
