Interference Cancellation for EDGE via Two-User
Abdulrauf Hafeez, Dennis Hui · 2003
EDGE has been introduced as an evolution of GSM for providing voice and high-speed data services. To cope with the ever-increasing demands on higher spectral efficiency, a tight frequency reuse (1/3 or even 1/1) may be adopted for GSM/EDGE in the foreseeable future, motivating the need to investigate advanced interference cancellation techniques. In this paper, we consider joint demodulation for cancelling a dominant cochannel or adjacent-channel interferer. A complete receiver structure is described assuming burst-synchronous users. Simulation results show that large performance gains are obtained with moderate receiver complexity in a dominant interferer-limited environ- ment.
