Signal Processing and Interference Suppression for Wireless Networks With Any Number of Users

In this paper, the authors investigate how to send space time codes with full diversity and low decoding complexity for Z channels with any number of users using precoders. First, they assume, that they have J transmitters and J receivers. Each transmitter sends code words to respective receiver at the same time. They 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 their best knowledge, this is the first general scheme which can achieve low-complexity decoding and full diversity for any transmitted code word in Z channel with any number of uses when all the users transmit at the same time.
