Implementable wireless access for B3G networks. III. Complexity reducing transceiver structures [Topics in Radio Communications]

This article presents a comprehensive overview of some of the research conducted within Mobile VCE´s Core Wireless Access Research Programme, a key focus of which has naturally been on MIMO transceivers. The series of articles offers a coherent view of how the work was structured and comprises a compilation of material that has been presented in detail elsewhere (see references within the article). In this article MIMO channel measurements, analysis, and modeling, which were presented previously in the first article in this series of four, are utilized to develop compact and distributed antenna arrays. Parallel activities led to research into low-complexity MIMO single-user space-time coding techniques, as well as SISO and MIMO multi-user CDMA-based transceivers for B3G systems. As well as feeding into the industry´s in-house research program, significant extensions of this work are now in hand, within Mobile VCE´s own core activity, aiming toward securing major improvements in delivery efficiency in future wireless systems through cross-layer operation
