In the strict sense, a closed-loop MIMO system requires the receiver to feedback some useful information to the transmitter for a better adaptation to the channel condition. On the other hand, an open-loop MIMO system dose not require any feedback information from the receiver. However, if adaptive modulation and coding is performed at the transmitter, both the closed-loop and the open-loop requires some feedback information to help the transmitter adjust the transmission rate according to the channel condition. This application of adaptive modulation and coding in MIMO systems raises an interesting question, that is if both equipped with adaptive modulation and coding, what is the throughput performance of the closed-loop MIMO system and the open-loop MIMO system under the same amount of total feedback bits? In this work, we have compared the throughput performance of the closed-loop and the open-loop systems with different number of feedback bits. Hsuan-Jung Su 蘇炫榮 2008 學位論文 ; thesis 60 zh-TW |
