[Modem program] Alamoutiwork DL : 0: 程序的主要功能是做了一定范围的信噪比下，对每个信噪比：随机信号QPSK调制；根据Alamouti方案的矩阵进行编码；发送信号经过瑞利信道和加入高斯白噪声；接收信号采用最大比合并的方法；最后对合并信号进行最大似然判决并求误符号率。结果表明10^-3对应大约12->13dB-Procedure main function is to do a certain range of SNR for each signal to noise ratio: random signal QPSK modulation program in accordance with Alamouti coding matrix send signals through Rayleigh channel and adding Gaussian white noise received signal using maximal-ratio combining method Finally the combined signal and the maximum likelihood decision for symbol error rate. The results showed that about 10 ^-3 corresponds to 12-> 13dB

[Modem program] ber DL : 0: In OFDM transmission, all the available subcarriers from the DFT is not used for data transmission. Typically some subcarriers at the edge are left unused to ensure spectrum roll off. For the example scenario, out of the available bandwidth from -10MHz to +10MHz, only subcarriers from -8.1250MHz (-26/64*20MHz) to +8.1250MHz (+26/64*20MHz) are used. This means that the signal energy is spread over a bandwidth of 16.250MHz, whereas noise is spread over bandwidth of 20MHz (-10MHz to +10MHz), i.e.
