| Software Defined Radio (SDR) is one of the key technologies in the future of wireless communication industry. A Tier-3 SDR, or Ideal Software Radio receiver is a device that performs all demodulation (RF, IF and baseband) entirely in the digital domain. In this work we present the design and implementation of AM and Short Wave receivers that belong to this type of ideal software radios. These receivers are implemented in Field Programmable Gate Array (FPGA) devices and we show how to integrate both receivers into the same device along with their performance measurements. The AM and Short Wave receivers have an equivalent gate count of 690,000 and 780,000 gates respectively. The device utilization of 4-input LUTs is 6% for the AM receiver and 25% for the Short Wave receiver using a Xilinx Virtex-E 2000 FPGA. The output SNR are 50 dB for the AM receiver and 55 dB for the Short Wave receiver using 8 and 9 bits of quantization respectively. |
