The errors caused in the wireless communication channel are very important to identify and rectify. Viterbi Decoder is very commonly implemented technique among the various error detection and correction (EDAC) techniques. A high data-rate convolutional code suffers from decrease in the performance of bit-error-rate due to inherent drifting error between the estimated and the accurate path matr...

This paper presents the laboratory test results of vertical infiltration on two soil columns of finer over coarser soils subject to simulated rainfalls under conditions of no-ponding at the surface and constant head at the bottom. The main objectives were to evaluate the effect of rainfall intensity and duration; and to provide experimental evidence for soil water redistribution and hysteresis....
