Software Defined Radio (SDR) is a flexible radio architecture which can be configured to adapt various waveforms, frequency bands, bandwidths, modes of operations and wireless standards such as Global System of Mobile communications (GSM) by altering the physical layer behavior through changes in its software. In this paper, The baseband section of GSM wireless receiver which includes Source Decoding, Channel Decoding, De-interleaver, Demodulation and Frequency De-hopping (FH) has been tested, simulated and designed for implementation using SDR. And the Bit Error Rates (BER) has been calculated for different modulation schemes namely, Binary Frequency Shift Keying (BFSK), Binary Phase Shift Keying (BPSK), and Quadrature Phase Shift Keying (QPSK), and Eight Phase Shift Keying (8PSK). These four models have been evaluated considering an additive white Gaussian noise channel (AWGN). Then the performance of the receiver has been analyzed by comparing the input and output waveforms with /without FH. Finally a comparison of the simulation results is presented and discussed.
