The submitted code attempts to model a a relatively practical 8PSK transmitter consisting of a bit stream generator a pair of modulators, RF up-converters along with a raised cosine filter, a digital to analogue converter (DAC) and a non-linear RF power amplifier (RF PA). The model could be used to assess the impact of the DAC's quantization noise, non-linearity of the RF power amplifier and an adjacent carrier along with AWGN on the receiver's performance. In addition to these, a phase imbalance and a phase offset could be added to the receiver's local oscillators. Phase noise could also be added to the local oscillators as a further enhancement.
发射机根据频率为“Fc”的载波信号的正弦和余弦分量调制星座位。接收机恢复符号乘以接收到的信号的正弦和余弦分量载波和集成结果的符号持续时间应用梯形规则获取接收的8 psk进行符号同步和正交组件是反过来用于识别合适的星座点，并进一步解码以获得位流。
