Receive Antenna Diversity Architectures for HSDPA

Receive diversity architectures for the high speed downlink packet access are investigated. Receivers combining the receive branches in the analog front-end are compared to single antenna receivers as well as two antenna receivers with combining in the digital baseband. Three methods maximizing the signal-to-noise or the signal-to-interference ratio are used for optimum combining. The simulations are performed in a link level simulator with data throughput as performance measure.
