Mobile CommunicationsThe signal transmitted by a Base Station has a power of 1 mW at a distance of 1 m from the transmitter. Measurements have shown that the propagation exponent for the path loss is n=3 up to a distance of 1 km and n=4 beyond that. For adequate signal quality, a signal to noise ratio of at least 15 dB is required. Find the maximum cell radius if an AMPS receiver with bandwidth 30 kHz and total noise figure (including the antenna) F=6 dB is used and (a) there is no shadowing, and (b) quality objective is to be met with probability 99% in the presence of log-normal shadowing with σ = 6 dB.
What RF bandwidth is required to send the data using QPSK? If the RRC filters in the transmitter and receiver are replaced with ones that have ? = 0.20, what are the new RF bandwidths in parts (a) and (b)?
Calculate the current in the output of the source before and after the installation of the new device and The temperature sensor output is a voltage which is equal to the temperature sensed by the sensor. Design an electric circuit which can get th..
Optimum length of the antenna to receive the FM station, An FM radio station transmits at a frequency of 99.9 MHz. A radio receiver has an antenna that is a quarter wavelength monopole consisting of a telescoping rod
