20090088146 | Methods And Devices For Uplink Load Estimation - An inherent non-observability of the thermal noise power level is circumvented by estimating an upper limit of the thermal noise power level by time evaluations. An instantaneous total received wideband power is measured in a receiver. Preferably, also an instantaneous sum of powers of all links used in the same cell is provided. A quantity (P′), preferably the difference between the instantaneous total received wideband power and the instantaneous sum of powers of all links used in the same cell, is followed ( | 04-02-2009 |
20100027590 | MODIFIED SIR VALUES FOR FAST POWER CONTROL - The present invention relates to a receiver comprising a fast power control unit, said fast power control unit being arranged to continuously control a quality measure of a radio channel. The receiver is characterized in that the quality measure is a modified Signal to Interference plus noise ratio (SIR) in which the influence from self interference has been removed. The invention further relates to a method for continuously controlling a quality measure of a radio channel, wherein a modified Signal to Interference plus noise ratio (SIR) is continuously determined in which the influence from self interference has been removed. | 02-04-2010 |
20100067511 | METHOD AND ARRANGEMENT FOR PREAMBLE DETECTION - In a hardware accelerator for preamble detection of a Physical Random Access Channel (PRACH) in a CDMA based communication system, buffering means stores input samples received at an antenna at a first rate, addressing means read a predetermined consecutive number of the input samples in parallel at a second different rate. The hardware accelerator is further partitioned into a reusable unit providing code correlation, and a preamble detection dedicated unit providing signature code despreading. The reusable unit comprises means for correlating at least a subset of the previously read input samples with a predetermined code to provide a correlation output for a number of time lags. The preamble detection dedicated unit comprises means for preamble detection configured for providing Hadamard Transformation of the correlation output to enable preamble detection, and all means are arranged on a single hardware chip to enable high-speed data transmissions between the respective means. | 03-18-2010 |
