| 摘 要： | 本文首先介强了非正交频移键控(frequency shift keying,FSK)信号的设计方法,然后介绍加性高斯白噪声信道和平坦Rayleigh衰落信道中非正交2FSK和MFSK信号的设计和检测.为了提高非正交FSK信号的性能,将高效的Reed-Solomon(RS)编码用于系统设计.研究结果表明,RS编码的非正交FSK系统可以获得频带利用率和性能的良好折衷.本文同时给出了RS编码非正交FSK信号的性能分析和相应的数值仿真结果.

| Abstract: | The design method of non-orthogonal frequency-shift key(FSK) signal is introduced in this paper firstly.Then according this method,the design and detection of non-orthogonal 2FSK and MFSK over additive Gaussian white noise channel and Rayleigh flat fading channel are considered.The Reed-Solomon(RS) codes are used to improve the performance of non-orthogonal FSK systems.It is showed that the tradeoff between performance and bandwidth utilization can be realized by RS coded non-orthogonal FSK systems.The performance analysis and numerical simulation are also presented in this paper. |
