使用高采样率的符号定时同步

Symbol timing synchronization usually relies on a digital PLL procedure, an iterative process that relies on detecting a timing error signal that is used to control an interpolation filter that in its turn tracks this error until lock is achieved. Suppose this feedback algorithm is totally ignored and brute force oversampling is used so that the maximum amplitude sample at the output of the matched filter would be the one to process further. so no tracking, no lock. Ignoring any small quantization error, are there any other issues using this method?Symbol timing synchronization usually relies on
