Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings.
[0030] figure 1 A schematic block diagram of a traditional multi-carrier transceiver system is shown, and the basic principle is summarized as the following steps:
[0031] Digital intermediate frequency up-conversion processing unit 101: perform up-conversion processing on the forward signals of the input M channel signals, modulate them to M carrier up-conversion frequency points according to the carrier information, and then combine and process the M channel signals to become Digital IF signal;
[0032] D / A conversion unit 102: convert the combined signal output by the digital intermediate frequency up-conversion processing unit 101 into an analog intermediate frequency signal;
[0033] Radio frequency transmission processing TX unit 103: filter the analog intermediate frequency signal output by the D / A conversion unit 102, modulate it onto the transmitting local ...

Based on forward directed and inverted directed channel selection information sent from channel allocation control unit, the channel signal allocation unit selects outputting forward signal of channel signal in M routes from shared units of forward channels. Meanwhile, the input baseband signals in M routes are allocated to signal in inverted direction on shared units of inverted channels corresponding to M routes in forward direction. Based on allocation information and command for channel signal, channel allocation control unit outputs selection information of forward and inverted channel signal. Based on allocation information and command for carrier signal, the carrier allocation control unit outputs M pieces of up-conversion carrier and M pieces of down-conversion carrier. The invention configures channel signal, carrier, and covering sector in multicarrier base system smartly, saves cost for covering network, and raises adaptability of system in complex environment.
Description
technical field [0001] The invention relates to a mobile communication base station system in the communication field, in particular to a multi-carrier transceiving system based on channel sharing and an implementation method thereof. Background technique [0002] In the current mobile communication base station system, the digital intermediate frequency method is generally used to realize the multi-carrier transceiver system, and the forward transmission link modulates, filters, amplifies and up-converts the digital baseband signal, thereby converting the baseband digital signal into a wireless radio frequency Signal, and then transmit the radio frequency signal through the power amplifier and antenna to complete the cell coverage function. The reverse receiving link receives the antenna signal, undergoes signal amplification, filtering, analog down-conversion into an analog intermediate frequency signal, and then A / D conversion, digital down-conversion, conversion into a b...
