about main project on UWB OFDM (FPGA VHDL)

Can anybody provide me reliable links about FPGA VHDL implementation of OFDM transceiver ?

Both baseband(FPGA) and RF-end (Non-FPGA)implementation desired.

Main blocks for implementation are FFT/IFFT,scrambler/de-scrambler,mapper/de-mapper,cyclic-prefix add/remove,coder/decoder,bit interleaver/de-interleaver, etc.

I am planning to implement this multiplexing technique for UWB MB-OFDM communication.
So, I have to design UWB Antenna,Low Noise Amplifier, PLL frequency multiplier, etc. on non-FPGA RF end.

MB OFDM- Multi-Band Orthogonal Frequency Division Multiplexing
UWB- Ultra Wide Band
