Bit Error Rate Performance of Single-RF Diversity Based on ESPAR Antenna
Minoru Okada, Satoshi Tsukamoto, Tomoya Kozu (NAIST) WBS2010-21
Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents a single-RF diversity scheme for spread spectrum
receiver based on IEEE 802.15.4 standard. The proposed scheme employs an
Electronically Steerable Passive Array Radiator (ESPAR) antenna with
periodically changing directivity at the symbol rate. IEEE 802.15.4
focuses on a low power consumption short range communication systems.
However, the bit error rate performance is not good enough in a severe
multipath fading environment. Diversity is a well-known technique to
compensate for the performance degradation due to multipath
fading. However, the complexity for diversity reception is a major
problem. In this paper, we propose a new single-RF diversity scheme
using ESPAR antenna with periodically changing directivity. The proposed
scheme is capable of obtaining the diversity gain in a frequency
selective fading environment and it solves the slow convergence rate
problem in the conventional ESPAR antenna based diversity
scheme. Computer simulation result and theoretical analysis show that
the proposed scheme gives diversity gain.
