Some radio systems suffer from multipath distortion, which is ca Some radio systems suffer from multipath distortion, which is caused by the existence of more than one propagation path between the transmitter and the receiver. Consider a channel the output of which, in response to a signal s (t), is defined by (in the absence […]

Repeat Problem 4.9 for the case of unipolar return-to-zero signa Repeat Problem 4.9 for the case of unipolar return-to-zero signaling, in which case symbol 1 is represented by a pulse of amplitude A and duration Tb/2 and symbol 0 is represent by transmitting no pulse. Hence show that this unipolar type of signaling requires twice […]

In 1880 five aboriginal trackers were each promised the equivalent of 50 Australian In 1880 five aboriginal trackers were each promised the equivalent of 50 Australian dollars for helping to capture the notorious outlaw Ned Kelley. In 1999 the granddaughters of two of the trackers claimed that this reward had not been paid. The prime […]

Repeat Problem 4.16, given that each set of three successive Repeat Problem 4.16, given that each set of three successive binary digits in the computer output are coded into one of eight possible amplitude levels, and the resulting signal is transmitted using an eight-level PAM system designed to have a raised-cosine spectrum. Is this the […]

Simplex (transorthogonal) signals are equally likely highly-corr Simplex (transorthogonal) signals are equally likely highly-correlated signals with the most negative correlation that can be achieved with a set of M orthogonal signals. That is, the correlation coefficient between any pair of signals in the set is defined by below, one method of constructing simplex signals is […]

In the noise analyzer of Figure a, the low-pass filters In the noise analyzer of Figure a, the low-pass filters are ideal with a bandwidth equal to one-half that of the narrowband noise n (t) applied to the input. Using this scheme, derive the following result: (a) Equation (1.101), defining the power spectral densities of […]
