Abstract:
A system and method are disclosed for performing ranging operations between two wireless devices without employing cyclic shift diversity (CSD) compensation techniques. For some embodiments, a first wireless device sends a negotiation request frame requesting the second wireless device to respond to subsequently received frames of a specified type using a selected one of the transmit chains in the second wireless device. Thereafter, the first wireless device sends a data frame to the second wireless device to initiate a ranging operation. The second wireless device sends a response frame of the specified type to the first wireless device using the selected one of the transmit chains.
