Abstract :
We propose a new receiver structure for GSM cellular systems. The receiver structure consists of an MMSE equalizer to mitigate the channel impairments separately followed by a Viterbi decoder for equalization of the GMSK signal (demodulation). Further, the proposed receiver structure can be incorporated with various antenna diversity schemes at the base station (BS) for GSM. Finally, a MMSE space-time receiver is proposed to mitigate both ISI and co-channel interference jointly. The improved performance is verified through simulation results
