    • Signals propagating in one communication channel can generate crosstalk interference in another communication channel. A crosstalk cancellation device can process the signals causing the crosstalk interference and generate a crosstalk cancellation signal that can compensate for the crosstalk when applied to the channel receiving crosstalk interference. The crosstalk cancellation device can include a model of the crosstalk effect that generates a signal emulating the actual crosstalk both in form an in timing. The crosstalk cancellation device can include a controller that monitors crosstalk-compensated communication signals and adjusts the model to enhance crosstalk cancellation performance. The crosstalk cancellation device can have a mode of self configuration or calibration in which defined test signals can be transmitted on the crosstalk-generating channel and the crosstalk-receiving channel.

    • A calibrating method for time-varying channel in a time-slot division mobile communication system is disclosed in the invention, including performing channel estimation and signal detection on a slot or abrupt received signals according to time- invariant block processing method; estimating the channel error by using the partial detection result close to the channel estimation code; utilizing the estimated channel error to modify the channel estimation; employing the modified channel estimation to demodulate the above mentioned detection result. This procedure can be performed once or several times. The present invention enables the block processing method adapt to some extent of variation of channel responses in a slot while maintaining its basic features, to achieve broadening slotted CDMA or the application range limitation of the block processing system, and also to improve the system performance in the case of larger frequency error, drifting and high-speed moving terminals.
