Channel Model - MATLAB & Simulink - MathWorks
What Is a Channel Model? A channel model is a mathematical representation of the effects of a communication channel through which wireless signals are propagated. The channel model can represent the power loss incurred by the signal as it travels through the wireless medium.
2007年2月21日 · This model of the medium is called channel model. In general, the power profile of the received signal can be obtained by convolving the power profile of the transmitted signal with the impulse response of the channel. Convolution in time domain is equivalent to multiplication in the frequency domain.
