Limited Feedback in MIMO

Recent field trials of LTE Advanced systems have shown very promising system performance. However, one of the challenges in such systems is the amount of side information required to be processed and shared among users. This information is dominated by the channel knowledge requirement. As such, the quantization of the channel information (or equivalently of the resulting precoding matrices) will play a crucial role in the overall system performance. The aim of the project is to study the effects of limited feedback in a Multi-Cell MIMO system, focusing on the development and the optimisation of adaptive codebooks for various channel conditions in Multi-Cell MIMO systems.
