The FPGA System for Evaluation of UWB Wireless Sensor Network Based on Transmitted Reference Integral Pulse Frequency Modulator

The paper presents implementation of FPGA system for evaluation of Ultra- Wideband (UWB) wireless sensor network based on transmitted reference integral pulse frequency modulator (IPFM) nodes and demodulator with embedded multi user coding and decoding scheme to provide multiple channel access. The simulation of multiple IPFM modulators and IPFM demodulator is performed in field programmable gate array (FPGA) assuming ideal transmitted pulse reception at the receiver side. The results are obtained by statistical analysis regarding various modulation parameters and number of IPFM modulators sharing the same communication channel.
