Threshold detection performance of GMSK signal with BT=0.5

This paper considers the detection performance of a serial thresholding receiver for precoded binary GMSK signal with BT=0.5. The conditional symbol (bit) error probability of the GMSK signal with carrier phase and timing errors is derived and compared to that of unfiltered BPSK. It is shown that the GMSK signal has practically the same performance as the ideal BPSK signal in the absence of sync errors and that the GMSK signal is more sensitive to carrier phase error but much more robust to symbol timing error than is the BPSK signal
