Digital filters are frequently designed by taking an analog (continuous-time) filter and converting it into its digital (discrete-time) equivalent. Linear, time-invariant discrete¬time filters with fixed sampling rates are usually designed by conversions from the analog using bilinear transformation. This book deals with conversions from analog domain into digital domain by higher order s-to-z transformations. By using higher order rules, we o...

This dissertation incorporates rate adaptation schemes for direct sequence spread spectrum systems. Subspace and pilot-aided methods for channel estimation can be used to estimate the nature of time varying channels. The simulated performance of punctured and repetition codes agrees well with the upper and lower theoretical bounds in hard-decision decoding over Rayleigh and Rician fading channels. The expression for the upper bound on soft-dec...
