Non-linear bandwidth reduction schemes for transmission of multivariate Gaussian sources over noisy channels

In this paper we investigate the design of bandwidth reduction non-linear schemes for the transmission of multivariate Gaussian sources over noisy channels. The non-linear mappings are designed utilizing an algorithm called “Power Constrained Channel Optimized Vector Quantization”(PCCOVQ). Practical examples for 2:1, 3:1 and 4:2 systems are provided, and simulation results are compared with the respective Optimal Performance Theoretically Attainable (OPTA).
