WCDMA Uplink Load Estimation With Generalized Rake Receivers
Torbjörn Wigren · IEEE Transactions on Vehicular Technology · 2012
A generalized rake (G-rake) receiver creates link gains by interference suppression. To fully exploit these gains for the enhancement of cellular system performance, the scheduler of a wideband code-division multiple-access (WCDMA) radio base station needs estimates of the uplink load after G-rake processing. This paper, therefore, proposes algorithms that estimate this load with a bandwidth as high as the channel estimation bandwidth. Link simulations support the obtained results.
