Question

In a baseband binary transmission, binary digits are transmitted by using

A*p(t) 0<t<Tb sending 1

-A*p(t) 0<t<Tb sending 0

The bit duration Tb second and the pulse shape is 

p(t) = 1-(|Tb-2t|)/Tb , 0<t<Tb

0 and 1 are equally likely. The channel noise is AWGN with power spectrum N/2.

a)Find the optimum reciever filter h(t) for sampling instant tm=Tb and sketch h(t) in the time domain

b)Determine the probability of error as a function of the Eb/N ratio

c)Compare the results in parts a) and b) for the case when the pulse shape is p(t) = 1-t/Tb , 0<t<Tb
