Abstract
La présente invention se rapporte au domaine des communications. L'invention concerne un système et un procédé d'étalonnage de récepteur entièrement numérique à grande vitesse fondés sur un codage entrelacé. Le système comprend un émetteur et un récepteur. L'émetteur comprend un démultiplexeur, un processeur de signal de bande de base, un dispositif de retournement et un multiplexeur. Le procédé d'étalonnage comprend les étapes suivantes : l'émetteur est démarré et des signaux de bande de base sont codés d'une manière entrelacée pendant un état initial de l'émetteur ; l'émetteur entre dans un état de fonctionnement normal et les signaux de bande de base sont codés normalement pendant l'état de fonctionnement normal de l'émetteur ; le récepteur effectue un traitement de signal numérique sur des signaux reçus afin d'obtenir des signaux de bande de base démodulés et vérifie en continu si les signaux de bande de base sont codés normalement ou d'une manière entrelacée ; après l'achèvement de l'étalonnage fin d'un convertisseur analogique-numérique (can) du récepteur, le récepteur entre dans l'état de fonctionnement normal. Selon la présente invention, un récepteur peut apprendre l'état de fonctionnement d'un émetteur et l'obtention par le récepteur de performances optimales peut être garantie.The present invention relates to the field of communications. A system and method for fully digital high speed receiver calibration based on interleaved coding. The system includes a transmitter and a receiver. The transmitter comprises a demultiplexer, a baseband signal processor, a flipping device and a multiplexer. The calibration method comprises the following steps: the transmitter is started and baseband signals are encoded in an interlaced manner during an initial state of the transmitter; the transmitter enters a normal operating state and the baseband signals are normally coded during the normal operating state of the transmitter; the receiver performs digital signal processing on received signals to obtain demodulated baseband signals and continuously checks whether the baseband signals are encoded normally or in an interleaved manner; after completion of the fine calibration of an analog-to-digital converter (CAN) of the receiver, the receiver enters the normal operating state. According to the present invention, a receiver can learn the operating state of a transmitter and obtaining optimal performance by the receiver can be guaranteed.
