| description | As a kind of spread spectrum technology, fast frequency hopping (FFH) system has good anti-jamming and anti-fading ability and has become the hot spot of frequency hopping communication research. The diversity combining technology is an indispensable key technical problem in FFH systems.
This dissertation mainly studies the diversity combining technology of Fast Frequency Hopping/Binary Frequency Shift Keying (FFH/BFSK) system, focusing on the performance analysis and simulation of diversity combining algorithms in different communication environments.
Firstly, this dissertation introduces the models of AWGN and Rayleigh fading channel, as well as the influence of PBNJ (Partial Band Noise Jamming) and MTJ (Multitone Jamming) on the channel. And this dissertation introduces some commonly used diversity combining algorithms and analyzes their pros and cons. Then the performance of these algorithms with different diversity order values and comparison over different channel environments are studied.
The performance of Noise-Normalised (NNORM) combining algorithm over Rayleigh channel with PBNJ and MTJ is studied in depth in this dissertation. The theoretical bit error rate expression and MATLAB simulation results are given. And the factors that affect the performance of the NNORM combining method are discussed. The performance of the NNORM combining receiver is compared with other receivers. |
