Implemention Of Automatic Modulation Recognition Algorithms Library And Remote CODEC

With the wide application in various fields, the importance of automatic modulation recognition which is one of the key communication has becoming prominent. Automatic modulation identification algorithm adopts extensive application of SOC hardware chip realization, SOC hardware chip platform has become algorithm testing and transformed into application of important basis. A eigenvalue discriminant automatic modulation identification algorithms and TI company developed heterogeneous dual-core high-performance processor OMPL137 were used to build a detection algorithm of assembly and the operation of the remote calls dual-core platform. In this paper, the three important part is Packaging automatic modulation identification algorithms, Dual-core remote calls algorithm and setting up the entire test platform.In this paper, wireless communication automatic modulation identification. algorithm of assembly and dual-core software framework development present situation, It is the main work of Automatic modulation recognition algorithm standard library the realization and the encapsulation of automatic modulation identification standard library of heterogeneous dual-core chips remote calling code realization. Based on automatic modulation and the algorithm identification algorithms standards and the key technology Codec search frame, this including automatic modulation recognition algorithm of dynamic and static memory allocation, ALG interface, IALG interface and some important data structure and function, etc. is used to perform automatic identification algorithms encapsulation modulation. Based on distance in the expanded Codec started,this including buried root and skeleton implementation and application layer interface implementation is used to complete algorithm remote calls realization. XDC tools configuration and compile operation code.Hardware platform using the EVMOMPL137 and server to structure; Software platform adopted Montavista embedded systems running on OMPL137 dual-core chips ARM end, use is DSP/BIOS system in OMPL137 dual-core chips DSP impetuously,use is the UBOOT1.3 guide ARM end, using DSP/BIOS LINK, using CMEM realize dual-core communication manage its share of memory.
