Embodiment Construction
[0019] The implementation of the intelligent network transceiver platform of the present invention will be described in detail below.
[0020] Frequency division duplex means that the transmission of the uplink and the downlink are carried out on different frequencies respectively. In the first and second generation cellular systems, FDD technology is basically used to realize duplex transmission. Especially in the first-generation cellular system, since the transmission is a continuous baseband signal, different frequencies must be used to provide duplex uplink and downlink channels. When FDD technology is used to transmit continuous information in the first generation cellular system, there must be a frequency synthesizer that generates different carrier frequencies at both ends of the transceiver, and there must be a duplex filter at the receiving end to prevent the transmitted signal from leaking to the receiver. In addition, in order to facilitate the production of duple...
