| 20090143039 | Radio reception apparatus and radio reception method - An RSSI detecting unit measures a receiving power level of a signal receive from a base station, and notifies a mode change control unit of the measurement result. A Ec/Io detecting unit measures a Ec/Io level of the signal received from the base station, and notifies the mode change control unit of the measurement result. The mode change control unit discriminates the change of the operation mode in consideration of not only the receiving power level, but also the Ec/Io level, and does not change the Simultaneous-Mode from the Hybrid-Mode unless at least the Ec/Io level exceeds a threshold line. | 06-04-2009 |
| 20090221253 | ADAPTIVE CONTROL APPARATUS USING MULTIPLE ADAPTIVE CONTROL METHODS - In the adaptive control apparatus, a computation unit computes weighting coefficients, using a first adaptive control method in a proportion α of a first computation amount, where the first adaptive control method has a first convergence rate and a first convergence error. Further, a computation unit computes weighting coefficients from initial values of the weighting coefficients computed by the computation unit, using a second adaptive control method in a proportion (1−α) of a second computation amount, where the second adaptive control method has a second convergence rate slower than the first convergence rate and a second convergence error smaller than the first convergence error. A controller controls determination of a ratio α/(1-α) based on a moving speed of a mobile unit, and controls the computation units to perform computing processes. | 09-03-2009 |
