Aimed at the antijamming needs of the space tracking. telemetry command (TT&C) receiver under a low signal-to-noise ratio. the anti-interference advantage of the dual-sequence frequency hopping (DSFH) communication system is applied. The channel amplitude fading influence of the receiver operating characteristics (ROC) of the TT&C receiver based on the DSFH is studied. https://echobookmarks.com/story19493393/penelitian-peningkatan-ketahanan-kikis-sol-karet-sepatu-olah-raga
