摘要： The apparatus contains a counter that is synchronized to the reference time in the mobile station. The counter counts sampled chips of the radio signal to produce a count. The apparatus further includes a controller that controls the processing of the radio signal, activates the processing of the radio signal when the count matches a begin count, and deactivates the processing of the radio signal when the count matches an end count, wherein the begin count and the end count are determined by a signal processor as a function of the time frame offset of the radio signal with respect to the reference time in the mobile station.

摘要： An apparatus and method for compensating for data distortion caused by the phase slew of a frame reference signal in a User Equipment (UE) that accesses an asynchronous Wideband Code Division Multiple Access (WCDMA) communication system are provided. In the distortion compensating apparatus, an Finite Impulse Response (FIR) filter receives I channel data and Q channel data, each of the I and Q channel data having a plurality of chips, multiplies the I/Q channel data by a predetermined filtering coefficient, and outputs the product, in synchronization with the frame reference signal. A phase compensator compensates for an I-Q channel exchange occurring at an output end of the FIR filter when the phase of the frame reference signal is advanced or retarded.

摘要： A receiver for the CDMA system, in order to reduce a power consumption during a suspension period of intermittent receiving operation, monitors a suspension period t1 by means of a low-power timer 51 so that a VC-TCXO 1, a reference signal group generation unit 2 and a receiving unit 3 are turned off and a modem unit 4 is set to a sleep state. Upon resumption of receiving operation, a high-accuracy timer 44 is supplied with a start (d) to require counting of time t3 and a part of a received signal is stored. A PN code phase of stored data is calculated in a PN code phase calculator 46 during a period t3 to obtain an indication value i for a phase deviation. State vectors for short code and long code and further a reception time t4 are calculated on the basis of the indication value i to be set. When the high-accuracy timer 44 counts t3 and produces 0V(d), demodulation operation by a rake demodulation unit 40, a demultiplexing unit 41 and a descrambler unit 42 is started in accordance with the setting and is continued during the reception time t4.

The method includes the steps of associating the master PN decade-code initialization t0 with a first time zone reference date and time and determining an elapsed time t1. The next steps equate the elapsed time t1 to a corresponding phase of the master PN code and synchronize the phase of the PN coded signal with the corresponding phase of the master PN decade-code.

摘要： A method and apparatus whereby a remote unit in a slotted mode wireless communication system may calculate accurate time throughout its entire active state. In the remote unit a “wall clock time” is calculated from a modulo 80 counter called a combiner time counter. When a remote unit enters its inactive state, counters within the remote unit, including the combined time counter, are deactivated. When the remote unit reenters its active state, the value in the combiner time counter may not be correct in relationship to slotted mode time. A controller in the remote unit forces the combiner time counted to the correct phase resulting in the combiner being within 26.66 of the correct value. The controller then determines a combiner offset to compensate for any remaining error in the combiner time counter. The control may then use the combiner time counter and the combiner offset to calculate accurate wall clock time. When convenient, such as at a slot boundary, the remote unit may reset the combiner counter to a correct value, and set combiner offset to zero.
摘要翻译：时隙模式无线通信系统中的远程单元可以在其整个活动状态下计算精确时间的方法和装置。在远程单元中，从称为组合器时间计数器的模80计数器计算“挂钟时间”。当远程单元进入非活动状态时，远程单元内的计数器（包括组合时间计数器）被禁用。当远程单元重新进入其活动状态时，组合器时间计数器中的值与时隙模式时间的关系可能不正确。远程单元中的控制器迫使组合器时间计数到正确的相位，导致组合器在正确值的26.66以内。然后，控制器确定组合器偏移量以补偿组合器时间计数器中的任何剩余误差。然后，控制可以使用组合器时间计数器和组合器偏移来计算精确的挂钟时间。当方便时，例如在时隙边界，远程单元可以将组合器计数器复位到正确的值，并将组合器偏移量设置为零。

摘要： Various techniques for improving a wireless communication device are described. The techniques may include reducing power in a wireless communication device for a first sleep period and then increasing power in the wireless communication device for an intermediate wake period after the first sleep period to estimate an error of the sleep clock. The method may further include reducing power in the wireless communication device for a second sleep period after the intermediate wake period. The intermediate wake mode implemented during the intermediate period can be used to estimate the error of the sleep clock without performing one or more tasks associated with an awake mode, such as demodulation. The techniques may facilitate the effective use of low frequency low power clocks for sleep mode, even when relatively large slot cycles are defined within a slotted paging system.
