Title
Wideband Ofdm Receiver Using Split Spectrum Processing
Abstract
A new wideband Orthogonal Frequency Division Multiplexing (OFDM) receiver based on split spectrum processing (SSP) technique is presented. In this receiver, the spectrum of the input signal is first decomposed into a number of sub-bands, and then independently down-converted to baseband for filtering and demodulation. This technique, which is characterized by the number of sub-bands and their bandwidths, reduces the sampling rate of analog-to-digital converter (ADC) by the sub-band bandwidth compared to conventional OFDM system. Analysis and simulation of the phase noise show that the new receiver exhibits the same bit error rate (BER) performance as the conventional OFDM system. Also, the Chebyshev II filter gives rise to superior BER performance compared to Butterworth, Chebyshev I, Elliptic, and Bessel filters. Interestingly, the traditional time domain synchronization algorithms can be employed for the new SSP receiver with only minor modifications.
