- This paper addresses multiple input multiple output (MIMO) techniques within 3G WCDMA. It begins with an overview of MIMO theory and presents WCDMA physical layer and recent high speed downlink packet access (HSDPA) enhancement to the WCDMA standard. Furthermore, MIMO channel models used in WCDMA performance evaluation were also discussed. The distance between base stations is of little influence on capacity loss of TD-SCDMA uplinks, while
the capacity loss of WCDMA uplinks will increase as the distance between base stations increases. The uplinks of WCDMA are of little interference to the downlinks of TD-SCDMA, which can even be ignored. The capacity loss of WCDMA uplinks will increase as the distance between base stations increases. To ensure that the capacity loss of WCDMA system is less than 5% at any offset distance, the ACIR should exceed 50dB. This paper presents methods for evaluating radio wave propagation, especially for cases where the base station antenna is below the rooftops, i.e. in the case of microcellular network environments. The developed microcellular propagation model has been developed for network planning purposes and it has been verified using numerous field propagation measurements, since there is often a gap between theory and practical implementation, prototyping is used to study the effects of real propagation channels, non-ideal RF equipment, and to understand complexity/speed/precision tradeoffs in algorithm implementation.
