TLDR
A low cost quadratic level compression algorithm is proposed for body sensor network system, which reduces the encoding delay and the hardware cost, while maintaining the reconstructed signal quality.Abstract:
A low cost quadratic level compression algorithm is proposed for body sensor network system. The proposed algorithm reduces the encoding delay and the hardware cost, while maintaining the reconstructed signal quality. The quadratic compression level determined by the mean deviation value is used to preserve the critical information with high compression ratio. The overall CR is 8.4:1, the PRD is 0.897% and the encoding rate is 6.4Mbps. The 16-bit sensor node processor is designed, which supports the proposed compression algorithm. The processor consumes 0.56nJ/bit at 1V supply voltage with 1MHz operating frequency in 0.25-μm CMOS process.read more
