Abstract

A software defined radio (SDR) prototype based on a multiprocessor architecture (MPA) is developed. Software for Japanese personal handy phone system (PHS) of a 2G mobile system, and IEEE 802.11 wireless LAN, which has a much wider bandwidth than the 2G systems, is successfully implemented. A newly developed flexible-rate pre-/post-processor (FR-PPP) achieves the flexibility and wideband performance that the platform needs. This paper shows the design of the SDR prototype and evaluates its performance by experiments that include PHS processor load and processing delay characteristics and wireless LAN processor load and throughput characteristics.
