Selection Combining (SC) receiver for Fast Frequency-Hopped Binary Frequency-Shift-Keying (FFH/ BFSK) communication systems can reduce the performance degradation caused by interference. The SC receiver model is proposed in the present of Partial Band Noise Jamming (PBNJ). The bit-error probability is evaluated for the receiver over a frequency-nonselective slowly Nakagami-m fading channel with PBNJ and additive white Gaussian noise. A closed-form error probability expression is given. It is shown that the SC receiver with high diversity order is immune to PBNJ and it achieves better performance comparing to several other combining receivers when the jamming power is strong. Under certain channel conditions, there is an optimal diversity order. An adaptive scheme is proposed for improving the performance of SC receiver when the jamming power decreases.
