A digital communication system involves with transmission and reception of digital data serially rather in the form of data blocks. Identify a suitable error control coding mechanism for faithful detection and control of bit error in the system to upgrade the system performance. Explain the encoding and decoding of the code sequence with suitable example.

1 Among various modulation schemes available for digital signals select the one that does not require carrier signal for demodulation, which is also called as non-coherent detection. Draw and explain the transmitter and receiver of the selected modulation scheme with suitable waveform representation. C HOD
