Design and performance evaluation of software defined radio prototype for PHS and IEEE 802.11 wireless LAN
نویسندگان
چکیده
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 IEEE802.11 wireless LAN, which has much wider bandwidth than the 2G systems, is successfully implemented. 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. Keywords―Software defined radio, PHS, wireless LAN, IEEE802.11, multiprocessor architecture, DSP, CPU, FPGA, over-the-air download.

This paper introduces Prawn, a tool for rapid prototyping communication protocols over IEEE 802.11 networks. Prawn provides a software environment that makes prototyping as quick, easy, and effortless as possible and thus allows researchers to conduct both functional assessment and performance evaluation as an integral part of the protocol design process. Since Prawn runs on real IEEE 802.11 no...
متن کاملNxWLAN: Neighborhood eXtensible WLAN
The increased usage of IEEE 802.11 Wireless LAN (WLAN) in residential environments by unexperienced users leads to dense, unplanned and chaotic residential WLAN deployments. Often WLAN Access Points (APs) are deployed unprofitable in terms of radio coverage and interference conditions. In many cases the usage of the neighbor’s AP would be beneficial as it would provide better radio coverage in ...
