Consider the 2-dimensional parity check code (PCC), in which a block of bits is
organized in a table (rows and columns) and a parity bit is calculated for each row
and column. Also, one more parity bit is added by adding (modulo 2) all the row
parity-check bits. Consider a block of 6 imes 6 data bits, there will be 6 row parity bits
and 7 column parity bits.
Calculate the transmission efficiency of this coding scheme. Determine the error
detection and correction capability of the scheme.
