Abstract

The invention discloses an LTE-Advanced air interface technology analysis device based on 8 channel carrier wave polymerization The LTE-Advanced air interface technology analysis device based on 8 channel carrier wave polymerization has big throughout and good instantaneity for operation processing like reception and detection of CA and eMIMO signals in a 8 channel, digital demodulation, decoding, analysis and transmission, and base band parallel processing and provides an integrated test device applicable to an LTD-Advance baseband, a physic layer, a physical layer and a high level protocol stack index test. The carrier wave polymerization LTE-Advanced air interface technology analysis device belongs to a desk type portable device, and is clear in design principle, reasonable in structure, easy to expand and low in cost. The LTE-Advanced air interface technology analysis device has following characteristics: 1 an independent 8 channel radio frequency design supports a CA test and an eMIMO test; 2 parallel 8 channel baseband performs synchronization processing and supports real-time demodulation of the physical layer; and 3 an embedded type FPGA + DSP + ARM architecture solves a high throughout parallel test. Through above arrangement, a 8 channel carrier wave polymerization LTE-Advanced air interface test demand is realized. Besides, the LTE-Advanced air interface technology analysis device can maximally support an air interface 8 antenna 5 carrier wave polymerization analysis real time processing, and is high in testing efficiency.

Description

technical field [0001] The present invention relates to an analysis device based on 8-channel carrier aggregation LTE-Advanced air interface technology. Background technique [0002] Today, with the rapid development of mobile Internet, the number of smart terminals has increased rapidly, which has led to a substantial increase in global data traffic. There is an increasing desire to transmit more data content wirelessly, such as higher quality video content. By providing 10 times the transmission rate of 3G, LTE-Advanced can provide users with a reliable wireless network experience. Network operators have evolved to LTE-Advanced due to factors such as competitive pressure, reducing network bearer pressure and cost driving. According to the Global Suppliers Association (GSA) report, as of July 2015, more than 143 countries had deployed 422 commercial LTE networks, of which 88 operators had launched LTE- Advanced commercial network is expected to reach 1 billion global LTE...
