Abstract

Some wireless communication systems must be able to receive and process signals from multiple source channels (stations) simultaneously. A common practice is to use multiple duplicated hardware resources; a different set of resources for each received channel. A new coherent Amplitude Modulated (AM) Time Division Multiplexed (TDM) receiver system architecture and design, based on the Software Defined Radio (SDR) standard, is proposed, developed and validated via simulation and experimental hardware prototype testing. The new receiver system architecture and approach enables reception and processing of signals from multiple channels using the hardware resources normally needed for reception and processing of only one channel. Production models of the proposed receiver/processing system architecture and design would be implemented to Programmable-Logic-Device (PLD) technology to accommodate rapidly changing communication protocols and standards and to enhance processing performance.
