[Program doc] gjlj DL : 0: 重点研究了低信噪比﹑多径瑞利衰落信道条件下，基于高阶累积量的OFDM信号盲识别技术。提出了利用奇数阶累积量区分OFDM信号与单载波信号的方法，并对基于三阶和五阶累积量的算法进行了仿真分析。 -﹑ Focus on the low SNR multipath Rayleigh fading channel conditions, based on cumulant OFDM signal blind identification technology. Made a distinction between the use of odd-order cumulants single-carrier OFDM signal with the signal approach, and based on the cumulative amount of third-order and fifth-order algorithm for the simulation.

[Program doc] HW4 DL : 0: A 16-QAM signal X, whose power is normalized as unity, is transmitted with OFDM over the discrete-time channel model h which has been used in Homework #2 and #3. As depicted in the below figure, the transmitter (TX) is now equipped with an N-point IDFT and the receiver (RX) with an N-point DFT, along with adding cyclic prefix (CP) and removing CP removal, respectively. The complex AWGN n is set with 20 dB SNR. Suppose that N=256 and the length of CP is 64. Assuming the OFDM system works with perfect synchronization. -Generate two pseudo random (PN) sequences for X, each with a length of 256 samples which are taken {+1,-1}, and add them before the 16-QAM data with a proper CP. The OFDM frame is depicted in the following figure. PN1 and PN2 are used for channel estimation now. Suppose the PN patterns are known at RX. Use the least squares (LS) method to estimate the channel by averaging the results obtained individually PN1 and PN2. (When perfoming the DFT window for the received signal at RX, you need to notice that the channel results in a delay of 22 samples.)
