Interference cancellation using antenna diversity for EDGE-enhanced data rates in GSM and TDMA/136

EDGE (enhanced data rates for global evolution) is one of the future wireless communication systems, offering high bit rates and packet data services. For data services an increased link quality will directly translate into improved throughput. A well-known technique that improves link performance is antenna diversity. Antenna diversity also enables interference-cancellation methods, which are evaluated in this paper. The conclusion is that introducing interference rejection in a GSM/EDGE classic scenario could increase average user bit rate by 26%. In a TDMA/EDGE compact scenario the average bit rate increase could be as high as 46% due to the time synchronized structure.
