TIMING PHASE ERROR CREATION METHOD FOR IMPROVING RESOLVING POWER OF TIMING PHASE ERROR FOR MEASURING THE PERFORMANCE OF DIGITAL RECEIVER

摘要

A timing phase error creation method for improving resolving power of a timing phase error for measuring a performance of a digital receiver is provided to enhance a speed of measuring performance of demodulation algorithm of the digital receiver by reducing a memory and a calculation quantity for measuring the performance. A timing phase error creation method for improving resolving power of a timing phase error for measuring a performance of a digital receiver includes a matching filter and a memory. An arbitrary time delay element is applied to the matching filter for creating the timing phase error as much as t time. The timing phase error is created by calculating a constant of the matching filter delayed as much as t by moving an input signal as much as t. The constant of the matching filter is changed according to the timing phase error by using the memory.
