我再论坛找了很多OFDM的代码和文章,但总有遗患,为什么呢原因是大部分只有简单的映射,IDFTDFT变换等等,但主要的同步和信道估计去没有人提出来,甚至做出来..
现在我终于找到了一份,它以FUNCTION的形式,再现了OFDM映射,IDFTDFT,同步(时间频率同步)和信道估计,以及频率偏移的估计等一系列代码.
The simulator GUI is started with command 'ui_start' in Matlab command window.
WLAN simulation starts by clicking the 'Start Simulation' button in the GUI window.
WLAN simulation can be terminated, before set number of packets have been reached by pressing 'control-C'.
