Abstract [en]

NOVELTY - The method involves providing multiple channel estimation in the field of space time coding in a radio communication system. Space time coding includes transmitter diversity, space(-time) multiplexing and other complex use of signal coding in time and space. USE - For wireless communication ADVANTAGE - Pilot signals are sent concurrently instead of consecutively in order to increase bandwidth efficiency during a multitude of channel transfer functions in OFDM and doing so, guaranteeing non-interfering channel estimates at low processing cost for both transmitter and receiver side. Provides channel estimation technique, which is very bandwidth efficient DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a wireless communication system, and an arrangement in a wireless communication system DESCRIPTION OF DRAWING(S) - The figure shows a schematic view illustrating pilot signal being sent concurrently.
