【简　介】:Abstract—We consider the design of channel codes for improving
the data rate and/or the reliability of communications
over fading channels using multiple transmit antennas. Data is
encoded by a channel code and the encoded data is split into
n streams that are simultaneously transmitted using n transmit
antennas. The received signal at each receive antenna is a linear
superposition of the n transmitted signals perturbed by noise. We
derive performance criteria for designing such codes under the
assumption that the fading is slow and frequency nonselective.
Performance is shown to be determined by matrices constructed
from pairs of distinct code sequences. The minimum rank among
these matrices quantifies the diversity gain, while the minimum
determinant of these matrices quantifies the coding gain. The
results are then extended to fast fading channels. The design
criteria are used to design trellis codes for high data rate wireless
communication. The encoding/decoding complexity of these codes
is comparable to trellis codes employed in practice over Gaussian
channels. The codes constructed here provide the best tradeoff
between data rate, diversity advantage, and trellis complexity.
Simulation results are provided for 4 and 8 PSK signal sets
with data rates of 2 and 3 bits/symbol, demonstrating excellent
performance that is within 2–3 dB of the outage capacity for these
channels using only 64 state encoders.
