Abstract
Layered space time codes (LST) have been shown to be an effective approach to increase the throughput of a multiple input and multiple output (MIMO) system. The performance of layered space-time trellis codes can be considerably improved if the channel state information is available at the transmitter and exploited for signal weighting across transmit antennas. In this paper, we consider joint transmit signal weighting through transmit power allocation and layered space-time codes to simultaneously optimize coding, diversity and weighting gains. Convolutional code is used as constituent code and an iterative parallel interference canceller (PIC) is employed at the receiver. A significant performance improvement is achieved compared to the conventional LST system with equal power allocation.
