“…The desired 160 kbit/s baud rate translates to a baud interval of 6.25 ps, so that the EC must be designed to operate on eight or more previously transmitted symbols. Previously reported EC's operate on samples taken at two to eight times the baud rate [15]- [17]. The penalty for oversampling by a factor k is that the complexity of the EC is proportional to k .…”

“…Sampleddata DSL timing recovery techniques have been reported, with a sampling rate from two to eight times the baud rate [15]- [17]. In an EC system, timing can only be derived from the received signal after EC, and therefore the sampling rate required by the timing recovery determines the sampling rate of the EC and, hence, its complexity.…”
