To Design the Communication System which transmits voice signal

The system needs to transmit a voice signal of 30 seconds.
(b) The transmitter supports BPSK, BFSK, and DPSK modulation schemes.
(c) Carrier frequency fc = 10 MHz.
(d) The communication channel has the impulse response as h(t) =
e
−αt , t ∈ [0, Ts), where α is the last two digits of your roll number.
(e) The noise added to the system is Gaussian in nature with zero mean
and a variance of 1.

Design the communication system with the following aspects:
(a) Record your own sound for 30 seconds to serve as the transmitted
signal.
(b) Find out the maximum frequency of the recorded signal and set up
the sampling frequency accordingly.
(c) Which modulation scheme leads to the least bit error probability for
your signal? Show that in your experiments.
(d) What is the difference in the bit error probability if a matched filter
is not used?
(e) Design the receiver and the reconstruction (Digital to Analog Converter)
to obtain the received signal.
