Abstract : The area of wireless communications is undergoing an explosive growth. Beingable to communicate anything, anywhere, has become an important part of our life.Resources such as power and bandwidth should be maximally utilized for transmissionof various signals, including speech, images and video. This underscores the impor-tance of deriving and approaching the information theoretic limits of transmissionover wireless channels.In this work, the problem of modeling time varying wireless channels is addressedand a finite impulse response (FIR) model is obtained, in which the coefficients aredescribed by a vector stationary, ergodic Gaussian process. This model is used toderive the information theoretic capacity of the wireless channel using the theory ofrandom matrices and random ergodic operators. -4 formula for capacity is obtainedin terms of the limiting function of the empirical eigenvalue distributions of channelmatrix operators of increasing size. The spectral theory of random operators providesa powerful characterization of the limiting function.Joint source channel coding of analog signals has been investigated on fixed FIRchannels, the random ergodic FIR channel model described above, and a finite stateapproximation of this FIR channel model under slow fading assumption. Channeloptimized vector quantization (COVQ) and optimal linear....-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
