QPSK在加性高斯白噪声环境下，信噪比和误码率的仿真。 先产生一个四组符号的序列，再将该序列映射到对应的相位上。用相应的函数产生均值为零、方差为δ2的加性高斯噪声。 (QPSK the additive white Gaussian noise environment, and the signal-to-noise ratio of the simulation. First group have a four symbols of sequence, then this sequence mapped to the corresponding phase on. With the corresponding function have zero mean and variance of 未2 additive white Gaussian noise.)

this explains about the concept of channel and fading related to it and about the ofdm concept.
