Abstract
In a wireless communication system, information is exchanged between a base station and a client station. The base station grants at least one allocation unit to a client station. The base station receives data from the client station using the allocation unit over the wireless link. The allocation unit substantially comprises mirror image pairs of subcarriers. Each mirror image pair of subcarriers includes a first subcarrier and a second subcarrier which are respectively disposed on opposite sides of a DC subcarrier by an equal frequency amount.
