Base on the results of FFT in OFDM demodulation, one new single frequency interference estimation scheme is proposed, which can estimate accurately the parameters of single frequency interference by analyzing two spectrum lines having higher energy than others. The complexity of the scheme is very low and its accuracy is much higher than that of the(More)
We propose a novel scheme of M-ary multicarrier spread spectrum based on wavelet packet. The scheme has good performance in multipath channel because of taking advantages of the properties of wavelet packet. Its performance is investigated for a multipath, slow Rayleigh fading channel. The performance advantages of the system over that based on DFT are(More)
