Implementation of generalized frequency division multiplexing system based on fast convolution
摘要
Abstract
This paper studied the implementation of generalized frequency division multiplexing system based on fast convolution,it included the system structure,the cyclic prefix and filter.It analyzed the system's symbol error rate,peak to average power ratio and complexity and simulated respectively.The studies showed that the fast convolution structure has a better symbol error rate and lower peak to average power ratio than traditional structure.When meet certain conditions,the system complexity will be lower than the traditional generalized frequency division multiplexing system.Based on fast convolution characteristics of flexibility,the fast convolution generalized frequency division multiplexing system also has the very high flexibility.By adjusting the parameters such as overlap factor and decimation factor,the performance of the system flexible can be adjusted flexibly.Choosing appropriate parameters,can make the system to achieve optimal performance.关键词
