Frequency Reconstruction Method of Non-uniform Data for Multi-channel Sampling Systems
Huiqing Pan, Shulin Tian, Peng Ye · Journal of Communication and Computer · 2010
In parallel time-interleaved sampling system, the timing mismatches between channels cause non-uniform sampling. Most original non-uniform reconstruction algorithms are very complex and not suitable for hardware realization. This paper presents a frequency reconstruction algorithm based on multi-channel processing. It decomposes the processing into low-speed channels that takes the advantage of parallel signal streams. Computer simulations and application results demonstrate this method could reconstruct the non-uniform signal effectively with less computation and higher real-time characteristic.
