Question

2.DT Equalizer Design. Direct Path Source Receiver Reflected Path Ground The multipath propagation channel of a wireless communication system involves three paths from the transmitter to the receiver: a direct path. an indirect path via a small reflector introducing a differential delay of 10us and signal gain of 0.1 -a second indirect path via a large reflector introducing a differential delay of 15us and signal gain of 0.2. The differential delays and the attenuations are measured with respect to the direct path. Assume a sampling frequency of 200kHz. 1. [3 pts] Formulate a discrete-time equation that relates the received signal to the transmitted signal, ignoring the presence of noise in the received signal 2. [4 pts] Find the structure of an IIR equalizer and identify its coefficients. Is this equalizer stable?
