Abstract:

The performance of an OFDM/OQAM system under phase noise is analyzed. The analysis helps to direct the design of low cost tuners through specifying the required phase noise characteristics. Discrete time formulation of OFDM/OQAM is first derived with the square root raised cosine(SRRC)filter as the pulse-shaping filter. Then the effect of multiplicative phase noise is equivalently represented as additive white Gaussian noise(AWGN), the variance of which is given analytically. We can observe that the same result as OFDM/QAM system is derived. Lastly, all the analytical results are verified by the bit error rate(BER)degradation through Monte Carlo simulation.

分析了相位噪声对OFDM/OQAM系统性能的影响, 分析的结果可用于指导设计低成本的调谐器.分析过程如下:首先导出了离散时间的采用SRRC成型滤波器的OFDM/OQAM系统公式;然后将乘性相位噪声等效表示为加性白高斯噪声, 并给出了解析的方差表达式, 该表达式与OFDM/QAM系统类似;最后利用BER的下降作为性能指标, 采用蒙特卡罗仿真验证了我们的分析结果.
