Interference Cancellation And Detection Using Precoders
Full Diversity Low Complexity
Next gen Wireless communication systems. Can be adopted for IEEE 802.11n, 802.20, 4G and WiMax standards.
The existing technologies used to avoid or reduce interference in wireless communication systems both lack effectiveness and consume valuable (expensive) bandwidth resources. The purpose of this UCI invention is to cancel the interference without using bandwidth, time, frequency, antenna or any other resources in the system. The main idea is to use channel information to cancel the negative effects of interference from other users. With a goal of achieving full diversity and low decoding complexity, researchers at UCI have designed, tested and evaluated novel precoders and quasi-orthogonal designs to achieve such a system. This development is the first known method that achieves full diversity without sacrificing bandwidth with a linear complexity.
