摘要： A set of channelization codes to be monitored is divided into two groups. The first group includes those codes for which an associated symbol modulation and transmit-diversity scheme is known. In the second group are those codes that are characterized by an unknown symbol modulation or unknown transmit-diversity scheme. The quality of the transmission of each code is then evaluated, using a metric. The metric in turn is used to determine whether the code should be used in estimating the covariance matrix by correlating the RAKE data corresponding to the code (i.e., by computing a correlation matrix for the code) or by first subtracting the channel estimates from the channel samples before correlation (i.e., by computing a covariance matrix for the code). An impairment covariance matrix is computed from the covariance matrices and correlation matrices so computed.

摘要： A shutter device for a still video camera comprises first and second shutter blades, a latch member and an unlatch member. The latch member latches the first blade at its moved position where an image pickup element is exposed to an image light. The first blade is kept latched for a preparatory exposure to correct a set exposure value on the basis of the output of the pickup element or for picking up a motion picture. The unlatch member releases the latching of the first blade. In one embodiment, the unlatch member is provided on the second blade to unlatch the first blade when the second blade is moved to terminate the exposure. In other embodiments, the unlatch member includes an electromagnet to unlatch the first blade.A still video camera comprises a view finder mirror and a mirror operating mechanism. The mechanism includes a motor and is arranged to retract and return the mirror relative to an optical path by utilizing a normal and a reverse rotation of the motor, respectively.In the disclosed embodiments, the camera further comprises a mechanism to maintain the mirror in the retracted condition and a shutter in the opened condition to operate in a motion video mode where an image pickup element is continuously exposed to an image light. The mechanism for setting in the motion video mode may be operable manually from the exterior of the camera or by connecting an external device to the camera.

摘要： The peak-index calculator calculates a peak index as an indication of PAR in accordance with gain factors β of channels. The coefficient selector includes a lookup table storing therein fitting coefficients X and Y each categorized in accordance with a combination of β, and selects coefficients X and Y each having a value determined in accordance with a combination of the gain factors β. The power-reduction calculator calculates a reduction in maximum signal-transmission power in accordance with both the peak index and the selected coefficients X and Y. The TXAGC calculator controls maximum signal-transmission power in accordance with the calculated reduction.

摘要： Adaptive reconfiguration of a wireless receiver is enabled based on channel geometry. According to an embodiment, the wireless receiver includes a geometry factor processing module and signal processing modules, e.g. such as but not limited to an SIR estimation module, a power estimation module, a despreading module, a low-pass filter, a combing weight generation module, a coefficient estimation module, a synchronization control channel interference canceller module, etc. The geometry factor processing module determines a geometry factor for the channel over which signals are transmitted to the wireless receiver, the geometry factor being a measure of the ratio of total transmitted power received by the wireless receiver to total interference plus noise power at the wireless receiver. One or more of the receiver signal processing modules are reconfigurable based on the geometry factor.
