What is a multipath channel?
Multipath channel (MPC) allows you to code a single transmission group for host-to-host communication that uses multiple write-direction, read-direction subchannels, as illustrated in Figure 1.
What is a channel response?
Ch Frequency Response is the frequency response of the channel calculated for each measurement channel. The channel frequency response spans the same bandwidth as the stimulus signal. Note this bandwidth can be different than the bandwidth shown in the Spectrum trace.
Why are wireless channels complex?
The wireless channel is different and much more unpredictable than the wireline channel because of factors such as multipath and shadow fading, Doppler shift, and time dispersion or delay spread. A mobile radio channel exhibits both time dispersion and frequency dispersion.

How is impulse response used in mobile radio?
Impulse response is wideband channel characterization and contains all information necessary to simulate or analyze any type of radio transmission through the channel. A mobile radio channel is modelled as a linear filter with a time varying impulse response, where the time variation is due to receiver motion in space.
What are the coefficients of the channel impulse response?
The channel impulse response is of length Nf, and the coefficients { fm (k)} represent the convolution of the transmit filter, the actual communication medium, and the whitening matched filter (WMF).
Which is the function of the channel response?
y(f)=H(f)x(f)+n(f) Here H(f) is channel response, and n(f) is the noise. Note that x, y, H, and n are all functions of the signal frequency f. The three key components of the channel response are path loss, shadowing, and multipath as explained below.
