Abstract
A transmitter () generates a first set of data symbols and a first pilot symbol () at a first time, and a second set of data symbols and a second pilot symbol () at a different, second time. The first () and second () pilot symbols are each represented by first () and second () pilot carriers, respectively, located at first () and second () predetermined sample frequencies, respectively, in a channel bandwidth. For the first pilot symbol (), the first () and second () pilot carriers have first and second predetermined values, respectively. For the second pilot symbol (), the first () and second () pilot carriers have third and fourth predetermined values, respectively. A receiver () measures the first, second, fourth and third predetermined values responsive to receiving the first () and second () pilot symbols to determine first, second, third and fourth estimates of channel distortion, respectively, for compensating and recovering the first and the second sets of data symbols.
