1. 1. Rise Over Thermal Estimation Algorithm Optimization and Implementation

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Saba Irshad; Purna Chandra Nepal; [2013]
   Keywords : Keywords: Enhanced Uplink E-UL ; Rise-over-Thermal RoT ; Thermal noise power floor; Uplink load; scheduling;

   Abstract : The uplink load for the scheduling of Enhanced-Uplink (E-UL) channels determine the achievable data rate for Wideband Code Division Multiple Access (WCDMA) systems, therefore its accurate measurement carries a prime significance. The uplink load also known as Rise-over-Thermal (RoT), which is the quotient of the Received Total Wideband Power (RTWP) and the Thermal Noise Power floor. READ MORE
