Abstract [en]

NOVELTY - The method involves compensating radio transmissions from a radio node using correction factor that is based on the representation of radio channel characteristics exchanged between the radio nodes. USE - For calibrating transmission portion of node in wireless communication network. ADVANTAGE - Enables achieving reciprocity between radio nodes, thereby optimizing coding and mapping at the transmitter which requires an accurate forward channel estimation hence communication performance is improved. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) communication system; (2) radio node; and (3) computer program comprising calibration program. DESCRIPTION OF DRAWING(S) - The figure shows the message sequence chart.
