Abstract: Focusing on the difficulties in communication networks test and optimization since some key technologies like carrier aggregation applied in communication networks, and the shortage of Long Term Evolution (LTE) air-interface analyzer in domestic market, a Long Term Evolution-Advanced (LTE-A) air-interface analyzer design scheme was proposed, which supports 3GPP R10/11 protocol standards and LET-A key technologies like carrier aggregation. Firstly, the physical and logical architecture of LTE-A air-interface analyzer was introduced, and the relationship between the two, the function of each module in the physical and logical architecture was illustrated, then an implementation scheme of carrier aggregation in the instrument was designed. At the same time, in order to meet the demand of new technologies in communication network as well as the requirements of users and base station equipment test, a scheme which could support multi-user in the case of multi-carrier and multi-cell for the analyzer was proposed. The application of the scheme, can accelerate the commercialization of carrier aggregation in communication network, speed up the network deployment process and shorten the network construction cycle, and it will play an indispensable role in communication network operation and maintenance.
