This project aim was to build wireless software modem for data communication between two computers using an acoustic interface in the voice frequency range (20Hz– 20,000Hz). The transmitting antenna is a speaker (frequency response of: 90Hz – 2

现在我终于找到了一份,它以FUNCTION的形式,再现了OFDM映射,IDFT/DFT,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.希望大家能从中得到你需要的东西. -Now I finally found a copy of it to the form of FUNCTION, reproduces OFDM mapping, IDFT/DFT, synchronized (time/frequency synchronization), and channel e

The Matlab code privided will generate OFDM symbol and will save the received symbols in two log file. Agorithm will determine Start point and carrier frequency off-set as a Synchronization block.
