1) Design the mathematical model for cyclic redundancy check arithmetic by considering the following assumptions \( T=n \) bit frame to be transmitted, \( D=k \) bit data to be transmitted, \( F=(n \) k) bits FCS? \( \quad P=n-k+1 \) bits predetermined divisor, \( Q= \) Quotient, \( R= \) remainder ( 10 mark) 2) With the help of the concept on error controlling using an FEC encoder and decoder in wireless communication Develop a block diagram after correcting the error if the input received is 11011 based on the coding table given below. Figure 1: Coding Table 3) With an illustration describe briefly the generalized block diagram of Digital Communication system.
