摘要： A system and method are described for dynamic temperature calibration of a frequency reference in a wireless base station. In a consumer grade base station, a reference oscillator may encounter frequency drift as the temperature of the base station changes. This causes interference as the transmission signal is not synchronized with other frequency resources in a network. An improved method of calibrating a reference frequency includes measuring a frequency difference between a frequency derived from an accurate reference frequency in a first base station and a frequency derived from a less accurate frequency reference in a second base station, determining a calibration factor for the offset, and applying the calibration factor to the base station to correct frequency drift. The calibration factors may be correlated with an operating temperature of the base station and stored in a temperature calibration table in the base station device.

摘要： A method and system that provides for execution of a first calibration sequence, such as upon initialization of a system, to establish an operation value, which utilizes an algorithm intended to be exhaustive, and executing a second calibration sequence from time to time, to measure drift in the parameter, and to update the operation value in response to the measured drift. The second calibration sequence utilizes less resources of the communication channel than does the first calibration sequence. In one embodiment, the first calibration sequence for measurement and convergence on the operation value utilizes long calibration patterns, such as codes that are greater than 30 bytes, or pseudorandom bit sequences having lengths of 2 N -1 bits, where N is equal to or greater than 7, while the second calibration sequence utilizes short calibration patterns, such as fixed codes less than 16 bytes, and for example as short as 2 bytes long.

摘要： A radio device includes an antenna (104), a transmitting circuit (102) and a receiving circuit (105) both sharing the antenna. During calibration, the output of the transmitting circuit is connected to the input of the receiving circuit to determine the amount of rotation of phase and/or amplitude variation of a signal passing through the transmitting and receiving circuits. A reference signal is fed to the input of the receiving circuit to determine the amount of rotation of phase and/or amplitude variation of the signal passing through the receiving circuit. By subtraction about the information, the amount of rotation of phase and/or amplitude variation of a signal passing through the transmitting circuit is determined, and from the information, the correction value for correcting the difference of the amount of rotation of phase and/or amplitude variation between the transmitting and receiving circuits is determined, thereby correcting the difference of the amount of rotation of phase and/or amplitude variation between the transmitting and receiving circuits.

摘要： A method and apparatus for estimating the downlink signature for a remote transceiver (141, 143) which is part of a wireless communication system that includes a main transceiver (101) for communicating with the remote transceiver (141, 143). The main transceiver includes an array of transmit antenna elements (105). The method uses the remote transceiver for receiving signals when the main transceiver transmits downlink calibration signals. When the main transceiver also has a receive antenna array, the remote transceiver can transmit uplink calibration signals to the main transceiver for determining an uplink signature. The downlink and uplink signatures are used to determine a calibration function to account for differences in the apparatus chains that include the antenna elements of the arrays, and that enable downlink smart antenna processing weights (118) to be determined from uplink smart antenna processing weights (115) when the main transceiver includes means for smart antenna processing according to weights.

摘要： A method and apparatus to control frequency deviation of a portable transceiver (PT) (122) utilizing a time-division-duplex (TDD) protocol for communicating with a base transceiver (116). The base transceiver (116) transmits (708) a first signal having first deviation levels (706). The PT (122) receives (802) the first signal, measures (808, 810, 824) it to derive estimates of the first deviation levels, and stores (826) the estimates in a memory (322). The PT (122) generates (828) a second signal having second deviation levels (830) controlled by control signal values (323), samples (832) the second signal to derive a second received signal, and appraises (902) the second received signal to derive estimates of the second deviation levels (830). The PT (122) compares (906) corresponding estimates of the first and second frequency deviation levels (830) to derive adjusted control signal values (908) for controlling the second deviation levels (830) to approximate the first deviation levels (706), and thereafter controls (914) the second deviation levels (830) in accordance with the adjusted control signal values (908).

摘要： An apparatus for detecting difference in operating characteristics of a main circuit by using a replica circuit is presented. In one exemplary case, a sensed difference in operating characteristics of the two circuits is used to drive a tuning control loop to minimize the sensed difference. In another exemplary case, several replica circuits of the main circuit are used, where each is isolated from one or more operating variables that affect the operating characteristic of the main circuit. Each replica circuit can be used for sensing a different operating characteristic, or, two replica circuits can be combined to sense a same operating characteristic.

摘要： A digital telemetry system can be calibrated to improve data communication. A receiver can receive a modulated signal with a predetermined sequence of transmitted symbols. A processing device can be communicatively coupled to the receiver for jointly performing carrier phase synchronization and symbol-timing recovery on the modulated signal to determine a corrective phase offset and a corrective timing offset. The receiver can be calibrated to use the corrective phase offset and the corrective timing offset for demodulating a subsequently modulated signal. In additional or alternative aspects, a demodulator can demodulate the modulated signal and determine an amount of interference introduced to the modulated signal. A transmitter can transmit data based on the amount of interference to a modem that transmitted the modulated signal for use by the modem to dynamically adjust bit allocation of the subsequently modulated signal.

摘要： A method for increasing an accuracy of a transceiver loopback calibration includes determining a time difference between the use of a local oscillator signal by a second mixing circuit within a receive path of the transceiver and the use of the local oscillator signal by a first mixing circuit within a transmit path of the transceiver. The method further includes delaying the local oscillator signal for the first mixing circuit or for the second mixing circuit to reduce the time difference; and performing a loopback calibration of the transceiver at the reduced time difference.

摘要： Various aspects described herein relate to calibrating transceiver impairment in wireless communications. Direct current (DC) components of one or more signals can be modified, using one or more configured DC components, for transmitting to a user equipment (UE) via a transmitter. A receiver can receive the one or more signals as transmitted via the transmitter. An impairment of at least one of the transmitter, the receiver, or a combination thereof, can be determined based at least in part on comparing the DC components of the one or more signals as received via the receiver to the one or more configured DC components. One or more components of at least one of the transmitter, the receiver, or a combination thereof can be adjusted to compensate for the impairment.
