A method for determining a symbol boundary of a data packet of a received signal, where the data packet includes a first training field, a guard interval, and a second training field. The received signal is sampled to obtain multiple samples. A first symbol boundary estimate is determined using one or more block auto-correlation values. Thereafter, a second symbol boundary estimate is determined based on the first symbol boundary estimate and using one or more cross-correlation values. The second symbol boundary estimate then is shifted using moving average auto-correlation values for the samples in the vicinity of the second symbol boundary estimate to obtain an accurate symbol boundary estimate.

A method converts an input data rate associated with N units of data to an output data rate associated with M units of data. The method includes calculating N write-control parameters each associated with one of M addresses of an output memory, directing each of N values of input data to an associated address of the output memory in response to the N calculated write-control parameters, and reading the output memory to provide output data associated with the output data rate. If N is greater than M, some of the N write-control parameters are associated with at least one shared address of the M addresses. If M is greater than N, all of the N write-control parameters are associated with different addresses of the M addresses. An apparatus is configured to implement this method.
