摘要

在移动衰落信道上传输需要一定的分集方案以获得较好的误码率。本文的目标是提出将编码调制与内置时分集、优化星座和多发射天线相结合的系统。传输系统在呈现多普勒效应的快衰落信道上进行模拟。与其他提出的系统相比，获得了12db的增益。

Fading-resistant transmission using built-in time diversity and several antennas

Transmission over mobile fading channels requires some diversity scheme to obtain better error rates. The objective of this paper is to present systems that combine coded modulation with built-in time diversity, an optimized constellation and multiple transmission antennas. The transmission systems are simulated over fast-fading channels that present Doppler effects. A gain of 12 dB is attained in comparison with other proposed systems.
