Following a procedure similar to that described in Section 2.11 Following a procedure similar to that described in Section 2.11 for the DSB-SC receiver, extend this noise analysis to a SSB receiver. Specifically, evaluate the followings: (a) The output signal-to-noise ratio. (b) The channel signal-to-noise ratio. Hence, show that the failure of merit for the […]
Figure depicts 32-QAM cross constellation. Partition this conste Figure depicts 32-QAM cross constellation. Partition this constellation into eight subsets. Ar each stage of the partitioning, indicate the within-subset (shortest) Euclideandistance.
Figure a, shows a non-coherent receiver using a matched filter Figure a, shows a non-coherent receiver using a matched filter for the detection of a sinusoidal signal of known frequency but random phase, in the presence o additive white Gaussian noise. An alternative implementation of this receiver is its mechanization in the frequency domain as […]
Equation (8.14) is one formulation of the Friis free-space Equation (8.14) is one formulation of the Friis free-space equation. Show that this equation can also be formulated in the following equivalent forms: where Pt is the transmitted power, At is the effective area of the transmitting antenna, ? is the carrier wavelength, d is the […]
Determine the transmission bandwidth reduction and average signa Determine the transmission bandwidth reduction and average signal energy of 256-QAM, compared to 64-QAM.
In a single-parity-check code, a single parity bit is appended In a single-parity-check code, a single parity bit is appended to a block of k message bits (m1, m2,,.., mk,). The single parity bit b1 is chosen so that the code word satisfies the even parity ride: m1 + m2 + . . . + […]

1. Trout Company is considering introducing a new line of pagers 1. Trout Company is considering introducing a new line of pagers targeting the preteen population. Trout believes that if the pagers can be priced competitively at $45, approximately 500,000 units can be sold. The controller has determined that an investment in new equipment totaling […]
Equation (6.47) is an approximate formula for the average probab Equation (6.47) is an approximate formula for the average probability of symbol error for coherent Mary P5K. This formula was derived using the union bound in light of the signal-space diagram of Figure b. Given that message point rn1 was transmitted, show that the approximate […]
