Transmit antenna selection (TAS) is a practical method to improve the bit-error-rate (BER) performance of a multiple-input multiple-output (MIMO) systems. TAS is of particulate importance when spatial modulation (SM) is ...

This study develops a new class of super-orthogonal trellis codes for four transmit antennas based on double space-time codes. The transmit antennas are divided into two groups, each having two transmit antennas. The ...

Trellis coded modulation (TCM) is a scheme that enhances the error performance without extra power not bandwidth. This paper presents a modified Super-Orthogonal Trellis-Coded Spatial Modulation (SOTC-SM) based on a cyclic ...
