Latest Patents
One of Jukka's latest patents is a method and apparatus to estimate signal to interference plus noise ratio (SINR) in a multiple antenna receiver. This invention provides a method to operate a receiver by applying signals received from at least first and second antennas to corresponding first and second finger pairs. Each finger pair comprises a first finger member and a second finger member, and the invention outputs traffic symbols and pilot symbols from each finger member. It also includes space combining weighted pilot symbols for each pair to produce a noise plus interference estimation for the pair under consideration. The cumulative noise plus interference estimate is generated by combining the noise plus interference estimation of each pair. This estimate is then subtracted from an estimate of the total signal energy input to a channel decoder to generate an unbiased total signal estimate. Finally, the unbiased total signal estimate is divided by the cumulative noise plus interference estimate to obtain an unbiased and accurate signal to interference plus noise ratio estimate that accounts for both space correlated and uncorrelated interference terms.
Another significant patent involves an apparatus and associated method for calculating communication channel indications for use in a radio communication system that utilizes closed-loop power control. This invention determines a carrier-to-interference ratio to be used in a closed-loop power control scheme, which controls power levels at which data is sent to a mobile station operable pursuant to a high-rate data communications service. A signal power level calculator calculates power levels of a pilot signal at successive power control group intervals. The calculations of the noise power levels are made, and a ratio of the values is formed. A report is generated and returned to a network part of the communication system, providing indications of the network part used to alter the power levels at which data is communicated to the mobile station.
