Designing Reliable Trans Multiplexers in Noisy Environments

Abstract

An optimum strategy for the design of trans multiplexer systems in the presence of noise is introduced. We consider the challenge of reducing the reconstruction error for a trans multiplexer system with fixed transmit terms and a target attenuation of crosstalk between bands. We may make the suboptimal reconstruction error system less vulnerable to variations in input signals and channel disturbances by using mixed H2/H optimization. Crosstalk between channels is to be anticipated due to the overlap of neighbouring subchannels. Crosstalk attenuation is posed as a H optimization problem and is decomposed into a set of linear matrix inequalities (LMIs). The simulation results show that the suggested design outperforms the state-of-the-art designs.
