摘要
超宽带(Ultra-Wide Band, UWB)系统目前可以实现600 Mb/s的高速率传输,但此速率传输模式的最大通信范围只能覆盖到3 m。为了提高超宽带系统传输性能,同时降低信道衰落效应,本文提出多输入多输出双载波调制解调技术,在保持原有带宽和天线发送功率的条件下,提高系统数据传输速率,扩大通信覆盖范围。理论分析和实验测试结果证实此调制解调技术使超宽带系统的数据传输速率最高达1.2 Gb/s和通信覆盖范围最远达4 m。
At present, Ultra-Wide Band(UWB) system can achieve 600 Mb/s high speed data transmission. However, the maximum communication coverage is about 3 meters. In order to improve its transmission performance and reduce the channels fading effect,Multiple-Input Multiple-Output(MIMO) Dual Carrier Modulation(DCM) scheme was proposed in this paper. The system channel capacity could be increased and the communication coverage could be expanded with remaining the bandwidth and antenna transmission power. Theoretical analysis and experimental results demonstrated the modulation and demodulation scheme could achieve the performance being 1.2 Gb/s with maximum wireless link coverage in 4 meters.
