Multi-scene random access method for tracking, telemetry and command communication system

The invention discloses a multi-scene random access method for a tracking, telemetry and command (TTC) communication system, and aims to solve the problem that the existing planned access TTC means cannot meet the TTC requirements of future space systems. The method is implemented by the following technical scheme: if the application scenario is a multi-beam full-space scanning access mode, a spacecraft continuously sends telemetry signals, a TTC communication system calls a scanning beam for full-space target search and identifies the received telemetry signals, and a remote control signal istransmitted to the spacecraft if the spacecraft is a cooperative spacecraft; and if the application scenario is an omnidirectional antenna-assisted access mode, the spacecraft periodically transmitsaccess beacons, telemetry signal parameters and ephemeris data of the spacecraft are obtained and sent to the TTC communication system, a tracking beam is called to capture, track and demodulate the telemetry signals sent by the spacecraft, the demodulated data is sent to a TTC center through an optical fiber, and the TTC center generates a remote control command and sends the remote control command to the spacecraft through the TTC communication system to complete random access.

Information safety transmission method based on non-associative artificial noise in untrusted relay system

The invention discloses an information safety transmission method based on non-associative artificial noise in an untrusted relay system. The untrusted relay system comprises a sending node A, a relay node B, a receiving node C and an interference node D. The information safety transmission method is implemented in the following steps: firstly, the interference node sends artificial nose so as to interfere a signal received by the relay node B at the first stage, thereby allowing the relay node B to generate an error code platform; and on this basis, the receiving node C processes signals from two stages by use of different criterions, so interference received by the signals at the first stage is recued, and the bit error rate of the receiving node C is effectively reduced. A simulation result shows that by use of the provided three strategies, namely the zero-forcing detection, the minimum mean squared error detection and the maximum likelihood detection, the bit error rate of the receiving node C is allowed to be apparently lower than that of the untrusted relay node B. Thus, safety is ensured and the performance of the minimum mean squared error detection and the performance of the maximum likelihood detection are similar and better than that of the zero-forcing detection.
