Q.2. Consider a black-and-white image, i.e. each pixel is either white or black. Let us denote white color by "1" and black color by "0". We want to send this image using pulses over a cable. Duration of a pulse is T sec.s and amplitude is A for " 1 " and A for "0". It known that 70% of the pixels are black but the receiver does not known which pixels are black or white. Moreover, the received signal is corrupted by zero-mean additive white Gaussian noise with a variance of 2. a) Design the maximum a posteriori probability (MAP) detector for this transmission. b) Design the maximum likelihood (ML) detector for this transmission
