High-power-double--lasers-Simulation

the comb pilot aided channel estimation in ofdm modulation is considered. the power of pilot subchannels is under the control. The data experience frequency selective channel then the AWGN noise is added to make the situation worse. The bit error rate is ploted versus SNR.

2FSK是利用数字基带信号控制在波的频率来传送信息。经过调制后的2FSK数字信号通过两个频率不同的带通滤波器f1、f2滤出不需要的信号，然后再将这两种经过滤波的信号分别通过包络检波器检波，最后将两种信号同时输入到抽样判决器同时外加抽样脉冲，最后解调出来的信号就是调制前的输入信号。(gudi hduidf hdag sdd w)
