Towards an IEEE 802.15.4 SDR transceiver

One of the goals of a software defined radio system is to be adaptable to send and receive data according to several specifications. That can be achieved if that system implements most of the communication operations, including physical layer tasks, in reconfigurable platforms. This paper introduces an all-digital transceiver based on the 868 MHz band of the IEEE 802.15.4 standard. The design consist of a transmitter with a bandpass delta-sigma modulator and an undersampling receiver. A Xilinx Virtex-5 FPGA is used to implement the proposed model.
