A FPGA Implementation of MMSE MUD Algorithm for TDRSS

Abstract

Multiple user satellites monitor is an important technology which can improve both the monitoring network coverage and the capacity of multi-target signal processing. Multi user detection (MUD) is one of the key technology for multiple user satellites communication. In this paper, a new algorithm for MUD is implemented on field-programmable gate array (FPGA). This FPGA design is based on the minimum mean square error (MMSE) algorithm which consists of two main components: Matched filter and minimum mean square error matrix. Additionally, in order to conduct Monte Carlo simulation, we adopt a way which based on Mat lab, UART and FPGA platform.
