1Performance Optimization of VLSI Transceivers for Low-Energy Communications Systems

Abstract—Design of low-energy communications systems requires atten-tion to power consumption in the overall system design and the algorithm implementations. We consider design of a communications system incor-porating digital transmission and receiver filters, and error-control coding. Various well-known channel codes including turbo codes, block codes, and convolutional codes are studied. For each of these decoders, its decoding performance and power consumption are evaluated from VLSI chip de-signs. We then demonstrate optimization of a simple design from a total system perspective.
