Lorenz-chaos

这是一个OFDM系统的信道估计仿真MATLAB，分析了基于训练序列的估计方法(This is an OFDM system channel estimation simulation MATLAB, analysis of the estimation method based on training sequence)

This is a model of a QPSK modulation system for transmission over a bandpass channel with fc = 100 Hz and B = 30 Hz and AWGN at the receiver. SRRC fi lters with excess bandwidth α = 0.18 are employed. The receiver includes an NDA timing recovery loop followed by a DD phase recovery loop. (This is a model of a QPSK modulation system f or transmission over a bandpass channel with fc = 100 Hz and B = 30 Hz and AWGN at the receiver. SRRC)
