Design and Implementation of 802.15.4 Transceiver for Wireless Personal Area Networks (WPANs) on FPGA

Abstract

The IEEE 802.15.4 standard provides mainly accessing, monitoring, and controlling capability of the Wireless devices. This standard supports short-range wireless communications and Low Rate (LR) - Wireless Personal Area Networks (WPANs). This manuscript presents the fully integrated digital 802.15.4 Transceiver, which suitable to ZigBee Device Standard at 2.4GHz range. The 802.15.4 Transceiver design includes an 8-bit input data sequence mapped to lower and Upper Symbols followed by Chip-sequence conversion as per the IEEE standard. The chip sequences are mapped separately as even and odd sequences used for the Offset-QPSK Modulation. The chip synchronization achieved by using a proper clocking mechanism on the receiver side. The 802.15.4 Transceiver design is implemented on Artix-7 FPGA using Xilinx Environment. The hardware constraints like Area (Slices), Frequency, and Power are analyzed. The proposed work also compared with existing similar approaches with more significant improvements in chip area and Power.
