Abstract

In this paper, we investigate how to send space-time codes with full diversity and low decoding complexity for interference channels using precoders. We assume that we have two transmitters and two receivers. Each transmitter sends codewords to respective receiver at the same time. We propose an orthogonal transmission scheme that combines space-time codes and array processing to achieve low-complexity decoding and full diversity for transmitted signals. To our best knowledge, this is the first scheme which can achieve low-complexity decoding and full diversity for any transmitted codeword in interference channel when all the users transmit at the same time. Simulation results validate our theoretical analysis.
