Example Q. Find the BER of a 100 kbaud, equiprobable binary, polar, rectangular pulse signalling ...
Binary data is to be transmitted using M-ary PAM over the ideal bandlimited passband channel with a bandwidth of B- 4 kHz. We use Raised Cosine (RC) pulses with roll- off factor γ 0.5 so that there is no ISI. If we want to achive a bit rate of 56 kbps, determine the required size of the signal set M, and the symbol rate.
Problem 2: An analog signal is to be converted into a PCM signal that is a binary polar NRZ line code. The signal is transmitted over a channel that is absolutely bandlimited to B-8 kHz. Assume that the PCM quantizer has 32 steps and that the overall equivalent system transfer function He is of the raised cosine-rolloff type with r 0.5. Find the maximum symbol rate D that can be supported over this channel without causing ISI a) c) Find...
A bipolar baseband binary signal has rectangular pulse level of +2 V or -2 V and bit duration of T. Additive white Gaussian noise with power spectral density No/2-10" Watts/z is added to it. Find the maximum bit rate that can be transmitted with a bit error probability of P 1?? using the following table of the Q function. Note: pa o 2E 2.33.1 374.2 0.01 0.0010.0001 0.00001 Q(x)
