“…Presence of cross-talk indicates the signal leakage from one sub-channel to another sub-channel which results in interference, and causes inefficient operation of transmultiplexer system. This is known as inter-channel interference or inter-carrier interference (ICI or E ICI ) and given as [31] …”

“…Still, there is no such iterative procedure reported in literature used for the design of CM TMUX by means of WCLS, which is capable to decrease the computation time, contrary in low number of iteration, and in addition, will also reduce the ICI, ISI, and maximize SICI, SISI, SI [31]. New proposed methods of filter design, transmultiplexer and its applications are given in [35][36][37][38][39][40][41].…”

“…Recently, a number of new methods have been presented for improving the recital of TMUXs by means of genetic algorithms (GAs), and artificial bee colony (ABC) algorithm [10]. In digital filter design, three most approximation criteria used are the least squares (L 2 ), minimax (L ∞ ) and peak constrained least square (PCLS) design criteria [2,[31][32][33]. The L 2 design norm is mainly used for digital filter design.…”

“…Different authors used different objective function and obtained the minimum possible value of reconstruction error in a filterbank. Since transmultiplexer is dual of filterbank [17], therefore similar optimization techniques can be applied to transmultiplexer with different objective functions [22]. In this proposed work, a single-variable optimization technique is used with ICI given in (4) as an objective function, i.e., [g(ω c ) = |E ICI (l)|].…”

This paper proposes an efficient approach for the design of M-channel maximally decimated near-perfect reconstruction (NPR) type transmultiplexer. Cosine modulation is used to design the synthesis and analysis sections of the transmultiplexer. The prototype filter is designed by using high sidelobe falloff rate (SLFOR) combinational window functions. A bisection-type optimization algorithm has been applied to minimize the interference parameters like inter-channel interference (ICI) and inter-symbol interference (ISI). The proposed algorithm has certain advantages than earlier reported work. The algorithm is of generalized nature, independent of the window function used in the design of the prototype filter. Second, it is fast and computationally efficient as only a single parameter is used as a variable which provides almost uniform interference level in all subchannels. Design examples are included for comparison with earlier reported work. Very small values of ICI and ISI have been obtained by using variable and combinational window functions.
