Direct RF pulse system helps in calculating

The received signal from a multipath channel is expressed as

Impulse response of a multipath channel is determined by the fact that

The effects of small scale multipath propagation are

Small scale multipath propagation is caused due to waves with

Coherence bandwidth is

The power delay profile helps in determining

If coherence time of the channel is smaller than the symbol period of the transmitted signal, it is

In Frequency Selective Fading, the
