| Abstract(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 sever 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 shceme is capable of obtaining the diversity gain in a frequency selective fading environment and it solves the slow convergence rate problem in the convenctional ESPAR antenna based diversity scheme. Computer simulation result and theoretical analysis show that the proposed scheme gives diversity gain. |
