摘要：

A design method of multiband orthogonal frequency division multiplexing ultra wideband (MB-OFDM UWB) baseband system using parallel structure is proposed. FPGA is used to design the transmitter and the receiver. The input of digital to analog conversion (DAC) module, the output of the analog to digital conversion (ADC) module, the synchronization module, the carrier frequency offset (CFO) estimation, and compensation module are all made up of four-channel parallel structures. The simulation results prove that, when the CFO and the sampling frequency offset (SFO) are up to +/- 20 ppm, in additive white Gaussian noise (AWGN) channel, CM1 or CM2 channel, the scheme ensures the low bit error rate (BER). It is suitable for high-speed MB-OFDM UWB system.
