Design & implementation of MQAM based IEEE 802.15.4/ZigBee Tranceiver using HDL

Digital MQAM Transceiver was implemented on FPGA for low cost, low power and simple wireless communication such as zigbee. The MQAM Transceiver primarily Transmit and receives on 2.4 GHz band. The Transceiver consist of chip generator, up-sampler, FIR filter, PISO(parallel in serial out), SIPO(serial in parallel out), FIR filter, down-sampler and chip-decoder blocks. These blocks are designed using Verilog in Xilinx ISE 13.1 and then implemented on Spartan 3 XC3S200E FPGA. Here to verify the functionality of receiver block the measurement & simulation results are also presented.
