而在《simulation and software Radio for mobile communication》的P87也是类似说法,“Gaussian noise is normally distributed equally in in-phase and quadrature-phase channels.” 原书中这里是基带仿真,没有上载波 可是注意到 \[E\left( {n\_tem{p^2}} \right) = E\left( {inois{e^2}} \right) ...

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...
