摘要：
Noise-Normalization Combining (NNC) is applied in Differential Frequency Hopping (DFH) receiver to improve the performance of DFH system in rejecting Partial-Band Jamming (PBJ). Symbol Error Rate (SER) performance of this receiver over Nakagami fading channel with PBJ and background thermal noise is analyzed and closed-form expression of SER is derived. A simplified expression for fading parameter m integer is derived based on moment generating function method. Simulation results show that for non-worst case PBJ, NNC-DFH receiver is superior to Linear Combining (LC) DFH receiver except when channel fading is weak and the jamming power is dispersed. Concentrating of the jamming power leads to more performance improvements. For worst case PBJ, this superiority always exists and is not affected by channel fading parameter and jamming bandwidth factor.
