为什么 attn_pow = 0.5*spow*sr/br*10.^(-EbN0(1,k)/10); 这一句有0.5这个系数,我当时很自然的回答噪声功率要分成I路和Q路,各占总噪声功率的一半。 而在《simulation andsoftware Radio for mobile communication》的P87也是类似说法,“Gaussian noise is normally distributed equally in in-phase and ...

[摘要]在数字信号的调制方式中4PSK是目前最常用的一种数字信号调制方式,它具有较高的频谱利用率、较强的抗干扰性、在电路上实现也较为简单。调制技术是通信领域里非常重要的环节，一种好的调制技术不仅可以节约频谱资源而且可以提供良好的通信性能。[关键词]4PSK； MATLAB ；调制 QPSK system simulation Author:B...
In recent years development in the field of communication lead to the development of modulation techniques. Selection of modulation techniques depends on signal to noise ratio (SNR), bit error rate (BER), Low multipath propagation etc. For this purpose QPSK (Quardrature phase shift key) and QAM...
