Wireless communications has been a topic of study since the 1960's. Two fundamental aspects of wireless communications make it challenging and interesting. First of all, the timevarying nature of the underlying channel due to smallscale and largescale fading is one of the most significant problems in designing wireless communication systems. Secondly, unlike wired communications in which each transmitterreceiver pair is isolated and can be thought of as a pointtopoint link, wireless communication users suffer from interference made by all other active users sharing the same transmission medium. A lot of effort has been done to improve the performance of wireless communication systems in the presence of fading and interference and this field is still attracting many researchers.
