Problems solved by technology

The former can only test a certain module, and cannot verify the reliability and real-time performance of the entire system; while the latter requires the integration of high-level protocol programs and mature network equipment, which often cannot meet the conditions in the initial stage of program development; During this period, regression testing on the physical layer needs to be performed separately. The current testing methods rely heavily on protocol codes, are costly and labor-intensive, and cannot achieve large-scale automated regression testing.

Abstract

The present invention relates to wireless communication system test technology, particularly relates to the physical layer test system and method based on ARM and DSP multi-core structure, said system includes control equipment, signal source, vector signal analyzer and tested terminal, said method includes multiple Step: The present invention realizes the separate test of the physical layer code in the wireless communication field without the upper layer protocol code, shortens the development and test time, reduces the test cost, and realizes the automatic test of the physical layer code conveniently and quickly.

Description

technical field [0001] The invention relates to a wireless communication system test technology, in particular to a physical layer test system and method based on ARM and DSP multi-core structures. Background technique [0002] A wireless terminal (or user equipment UE) can be divided into a physical layer (PHY), a data link layer and a radio resource control layer (RRC) from the protocol, and the data link layer includes a media access control layer (MAC) and Radio Link Control (RLC layer). The physical layer is located at the bottom of the protocol model, and mainly completes the process of channel encoding and decoding, physical channel mapping and demapping, and modulation and demodulation; the physical layer obtains interlayer primitives from the MAC and sends them to or from the peer entity and other entities receive data and signaling. The MAC layer is located above the physical layer, and mainly completes processes such as data framing, error detection and retransm...
