Summary :

This paper describes the predemodulation filtering effects on the bit-error-rate (BER) performance and the optimum predemodulation Gaussian band-pass filter (BPF) for MSK with 2-bit differential detection. It is derived that the optimum BT product for 10-3 and 10-6 BER is 1.0 and 1.2 with 3.2 dB and 3.8 dB Eb/N0 degradation from the ideal coherent transmission system, respectively. It is also shown that the BER performance of 2-bit differential detection for BT1.5 is better than that of conventional 1-bit differential detection by 0.2 dB to 2 dB.
