Abstract :
Space-time trellis codes can achieve the best tradeoff between bandwidth efficiency, diversity gain, constellation size and trellis complexity. We propose some optimum low rate space-time trellis codes. Performance analysis and simulation show that the low rate space-time trellis codes outperform space-time block codes concatenated with convolutional code at the same bandwidth efficiency, and is more suitable for the power limited wireless communication system
