“…Here the step size is chosen as a fraction of transition width as [10] since the proper selection of stepsize plays an important role to achieve minimum amplitude distortion for different values of subbands . In case of ideal channel, the interchannel interference should be zero.It is not true for real time system due to non ideal nature of filters.Hence the interchannel interference is estimated by…”

In communication systems, techniques which provide high resistance against Interchannel Interference under high data rate transmission become vital [1]. Hence, an efficient algorithm for design and implementation of non-uniform digital filter banks using optimization parameters is presented. The design problem is based on unconstrained optimization of cut-off frequency (ωc) for Finite Impulse Response (FIR) filter banks for optimum design of transmultiplexer depending on near perfect reconstruction [2]. The objective function is chosen as Interchannel Interference and amplitude distortion (Eam) with ωc, As, and roll off factor as varying parameter [3]. The proposed algorithm will be validated for real-time video processing with 40dB attenuation, which are sufficient to ensure an output of adequate quality.
