Abstract
Software Defined Radio (SDR) has been identified as one potential method to enhance the flexibility of wireless communication systems. In the past, the operating speed limitation of analog digital converter (ADC) and processing ability limitation of re-configurable chips for signal processing have slowed down the development of SDR for useful commercial application. With recent advances in the semi-conductor processing technology and the development of re-configurable devices such as digital signal processors (DSP) and field programmable gate arrays (FPGA), SDR has now become practical for use in system solutions including wireless LANs, audio and television broadcasting and interoperability between different radio services. In this paper, we describe the application of SDR based on Six-Port technology to provide multi-channel, multi-mode wireless digital receiver. The combination of SDR and Six-Port technology provides a great flexibility in system configuration, a significant reduction in system development cost, and also a high potential for software reuse.
