Abstract
A method of determining a time slot timing based upon an input sequence r(n) is disclosed. The method comprises using a frequency correction channel detector to determine a first time slot end time based upon the input sequence r(n). Then, the frequency correction channel detector is used to determine a second time slot end time based upon an order reversed input sequence r(n). A time slot midpoint is calculated as the average of the first time slot end time and second time slot end time. The time slot midpoint is then used to estimate the time slot timing.
