Abstract

The invention relates to a multi-dimension hybrid spread spectrum system and method based on a high speed bus and a graphic processing unit (GPU), belonging to the technical field of communication. The multi-dimension hybrid spread spectrum system comprises a transmitting unit, a GPU, a receiving unit and a data main control unit, wherein the transmitting unit comprises a transmitting antenna, a transmission radio-frequency module and a low and medium frequency / baseband transmitting module; the receiving unit comprises a receiving antenna, a reception radio-frequency module and a low and medium frequency / baseband receiving module; and the data main control unit comprises a high speed bus and a main control / buffer and display module. The invention adopts the technologies of multi-input and multi-output, space-time coding, parallel processing and high-speed transmission reception diversity, and combines a direct spread / frequency hopping hybrid technology, so that the overall system integrates the advantages of three dimensions of space, time and frequency, and the confidentiality and anti-jamming ability of the realized hybrid spread spectrum system are further greatly expanded; and very quick data transmission and quick code synchronization and code acquisition performance of the multi-dimension hybrid system are realized by the advantages of the high speed bus and GPU architecture.

Description

technical field

[0001] The invention relates to a multi-dimensional hybrid spread spectrum system and method based on a high-speed bus and a GPU, belonging to the technical field of communication. Background technique

[0002] Today, with the rapid development of communication, the electromagnetic environment is becoming more and more complex, and the requirements for the anti-interference ability of communication systems are also getting higher and higher. The complex communication environment requires a new architecture system, so the design and implementation of a communication system with strong survivability and minimum communication guarantee has become the top priority of today's research.

[0003] The direct spread system is conducive to the concealment of the signal, and has strong anti-jamming, confidentiality and anti-multipath capabilities. The frequency hopping system has a strong ability to resist multiple types of interference such as pulses, but the anti-mul...
