Detailed Description
As shown in fig. 1, the invention provides an anti-interference carrier aggregation communication terminal, which comprises a main control module, a signal coding and decoding module, a channel coding and decoding module, a radio frequency front-end filter, an analog-to-digital converter, a time sequence control module, a receiving module, a transmitting module, an analysis module and an aggregation module, wherein the signal coding and decoding module is electrically connected with the periphery of the main control module.
Additional transmit antenna ports are provided on the main control module for supporting multi-antenna transmission of multiple data streams downstream. The data downlink supports the joint transmission of a plurality of LTE Release-8 carriers. The radio frequency front-end filter is used for carrying out sharp filtering on a channel of a required signal through a series of digital filters in the DFE and realizing the required signal-to-noise ratio by fully rejecting various types of retarders; the receiving module is used for converting the sampling rate of the analog-to-digital converter and filtering out the residual interference after the radio frequency front-end filter plays the roles of initial wave band and channel selection; the analysis module is used for judging whether the first carrier is interfered or not according to the background noise of the first carrier; and the aggregation module is used for realizing data downlink by using the downlink frequency band aggregated by the first carrier and the second carrier.
In the LTE-Advanced Release-10 stage, the terminal supporting the enhanced multi-antenna technology is extended to parallel transmission of maximum 8 data streams in the downlink and parallel transmission of maximum 4 data streams in the uplink, wherein the introduction of the enhanced uplink multi-antenna transmission technology has the greatest influence on the radio frequency design of the terminal, because in the LTE Release-8 stage, the terminal supports multi-antenna transmission of maximum 4 data streams in the downlink and only supports single-antenna transmission in the uplink.
A terminal supporting the LTE-Advanced uplink multi-antenna technology needs to add at least one transmitting antenna port. The enhanced uplink multi-antenna terminal radio frequency performance index is defined in the 3GPP standard specification TS 36.1016, and the difference between the enhanced uplink multi-antenna terminal radio frequency performance index and the single-antenna radio frequency performance requirement is that the terminal radio frequency index definition comprises two types: antenna port definition based (Per Antenna) and terminal definition based (Per UE). For example, the index of the maximum transmitting power of the terminal is defined for each terminal, and the sum of the port powers of the transmitting antennas needs to meet the requirement of the maximum transmitting power specified for a single antenna in LTE Release-8 (not more than 23 dBm); the index of the terminal spectrum radiation template is defined for each antenna port, and the transmitting power of each antenna port needs to meet the maximum transmitting power specified for a single antenna in LTE Release-8.
