BACKPROJ uses the filtered or unfiltered backprojection algorithm to perform the inverse Radon transform. The filter is designed directly in the frequency domain and then multiplied by the FFT of the projections. The projections are zero-padded to a power of 2 before filtering to prevent spatial domain aliasing and to speed up the FFT.

循环谱代码，以及MFSK的循环谱代码的实现(Cyclic spectrum code, and the code MFSK realization of cyclic spectrum)

this code is usefull to calcule the hydraulics properties for a given cross section or batymetric. Also plot the manning properties vs de hydraulic depth

one of the best ways to have a blind channel estimation is using a precoding after before IDFT operation in OFDM systems,this simulation shows the precoding infulence on the system.
