Abstract
An analog space-time relay method and apparatus for a wireless communication relay channel is disclosed herein. In a specific embodiment, the analog space-time relay channel () includes first and second relay antennas () arranged to relay an information signal transmitted from a source station () to a destination station (). The method comprises the steps of: (i) receiving a first symbol sequence at the first relay antenna (), the first symbol sequence comprising the information signal and a first noise element; (ii) receiving a second symbol sequence at the second relay antenna (), the second symbol sequence comprising the information signal and a second noise element; (iii) transmitting a first signal by the first relay antenna (), the first signal being associated with the second symbol sequence received at the second relay antenna (); (iv) transmitting a second signal by the second relay antenna (), the second signal being associated with the first symbol sequence received at the first relay antenna (). Method and apparatus for deriving a complex conjugate for a symbol sequence and a frame header structure are also disclosed.
