    摘要: The present invention provides a multimode communication terminal which contains at least a first separate channel module and a second separate channel module. The multimode communication terminal can be configured to communicate by using the first channel module and/or the second channel module. The channel modules communicate according to different communication protocols. The multimode communication terminal further comprises: channel switch layer means for switching the first channel module to have parameter characteristics consistent with those of the second channel module, so that the multimode communication terminal enables the MIMO operation mode by using the first channel module and the second channel module at the same time. The present invention further provides a method for enabling a MIMO operation mode in a multimode communication terminal. By using a relatively small number of RF communication modules, the present invention implements a wireless mobile multimode communication terminal which enables various operation modes including the MIMO operation mode. Compared with the existing solutions, the present invention greatly reduces the size required by the terminal.

    摘要: A method for enabling a MIMO operation mode in a multimode communication terminal includes switching a first channel module to have parameter characteristics consistent with those of a second channel module, so that the multimode communication terminal enables the MIMO operation mode by using the first channel module and the second channel module at the same time. The method also includes extracting corresponding parameters from the second channel module and configuring the first channel module to be switched with the extracted parameters, such that the first channel module and second channel module enable the multimode communication terminal to perform MIMO communication. The method further includes issuing, upon determination of a switch, notification instructions to means in channel switch layer means and changing a data channel associated with the first channel module, such that the first channel module and second channel module can be adapted to the MIMO operation mode.

    摘要: A device and method for compensating for delays of a plurality of communication channels, provides signals with a certain frequency range, wherein the signals form standing waves in the plurality of communication channels; calculates phase differences between the plurality of communication channels according to the signal frequencies at the peak values of the standing waves; and determines the delay of each communication channel according to the above phase differences. The device and method may be applied to the communication channels of high speed parallel connection to eliminate the delays of the communication channels and realize length matching. Since the device and method determine the delays of communication channels by means of the phase differences, even when the delay difference exceeds a clock cycle, it can calculate the phase differences properly.
