A signal is transmitted using a carrier frequency of 900 MHz. It is transmitted through a multipath channel which can be modelled as Rayleigh fading. Assumingthe Dopper spread as 10Hz and the number of multipaths as 10, generate the Rayleigh faded signal. Compute the outage rate (the probability of the signal falls below certain rate, say ?10 dB) of the signal. Using MATLAB, demonstrate the path loss as a function of loss parameter for distances ranging from 2 km to 40 km. Calculate the power loss in dB

Abstract— We propose a simple speech compression algorithm using subband division and ADPCM (Adaptive Differential Pulse Code Modulation) algorithm. Although speech data are stored in a semiconductor memory device, its capacity and the available network capacity are limited. Therefore, it is necessary to compress the data as much as possible. The first is that the reconstructed datum must be understood correctly. Speech signal is compressed with a ratio of 1/4 using the proposed subband division and ADPCM (Adaptive Differential Pulse Code Modulation) algorithm.
