Abstract
En 中文
This paper presents a study of the performance of the first-order time-delay digital tanlock loop (TDTL). It proposes a I number of modified loop architectures that overcome some of the original TDTL design limitations. Simulation results indicate that the new architectures, which include delay switching, gain adaptation and a combination of both techniques, improve the TDTL performance in terms of acquisition speed, locking range and resilience to frequency disturbances. The first-order TDTL was also implemented on a field programmable gate array (FPGA). The real-time results from the FPGA implementation are in agreement with the ones obtained through simulation.
