Untuk sistem TSTD (Time Switched Transmit Diversity) bantuan permintaan ulang automatik (ARQ), penerima menghantar isyarat pengakuan (ACK atau NACK) kepada pemancar untuk meramalkan keadaan saluran. Dalam makalah ini, dua skema pensuisan antena, di mana NACK mencetuskan pensuisan antena pemancar dalam corak pensuisan antena yang dicadangkan, dicadangkan untuk TSTD dengan ARQ dalam sistem WCDMA LCR-TDD. Di samping itu, prestasi sistem disiasat. Keputusan simulasi menunjukkan bahawa prestasi sistem TSTD boleh dipertingkatkan dengan menggunakan skema ARQ. Tambahan pula, prestasi sistem TSTD berbantukan ARQ mungkin dipertingkatkan dengan ketara dengan menggunakan skema pensuisan antena yang dicadangkan, terutamanya apabila kelajuan mudah alih rendah.

Abstract: For automatic repeat request (ARQ)-aided TSTD (Time Switched Transmit Diversity) system, a receiver sends the acknowledgement signal (ACK or NACK) to a transmitter in order to predict the condition of the channel. In this paper, two antenna switching schemes, in which the NACK trigger the transmit antenna switching in the proposed antenna switching patterns, are proposed for the TSTD with the ARQ in WCDMA LCR-TDD systems. In addition, the system performances are investigated. Simulation results demonstrate that the performances of the TSTD systems can be improved by applying the ARQ scheme. Furthermore, the performances of ARQ-aided TSTD systems may be significantly improved by applying the proposed antenna switching schemes, especially when the mobile's speed is low.
