Investigations on AQ-DBPSK Modulation based RF Transceiver for Wireless Sensor Communication Networks
Authors: ,
Abstract: This research work demonstrates the simulation results of a Radio Frequency (RF) transceiver with Alternate Quadrature Differential Binary Phase Shift Keying (AQ-DBPSK) modulation at 2.4GHz. The RF transmitter consists of an AQ-DBPSK modulator, an up conversion mixer, a 2.4 GHz Band pass filter and a power amplifier. At the receiver RF front end, the Low Noise Amplifier (LNA), mixer with down conversion to Intermediate Frequency (IF), a Low Pass Filter (LPF) and an AQ-DBPSK demodulator is used. The block level parameters of the transmitter and receiver RF front end like Noise Figure (NF) and Gain are optimized to meet the transceiver specifications for the applications in Wireless Sensor Communication Networks.
