| 中文摘要 | This paper presents a low-power digital receiver structure for multi-speed HART which can adaptively demodulate input signal modulated in non-coherent HART FSK or coherent HART C8PSK. A new kind of CSD coded preset equalizer is introduced according to the characteristic of HART channel distortion. Synchronization is divided into initialization stage and tracking stage. In initialization stage, it attains equilibrium state quickly and reduces tracking computation rate, while in tracking stage, it is time-divided carried out and reduces the computation rate of the equalizer and interpolator. Additionally, a novel algorithm is developed for HART FSK demodulation reusing the resource as HART C8PSK. Power consumption can dramatically decrease, because Multiplications used per one symbol demodulation are dramatically reduced; while simulations show that the proposed structure can convergence fast and work very well in low SNR. |
