Abstract [en]

NOVELTY - The method involves determining value of sensitivity related to non-ideal characteristics of transmitter for each modulated packet data unit (PDU). The determined sensitivity value for each of modulated PDU per flow is compared, based on measured modulated PDUs. The modulated PDU with the lowest sensitivity value is selected and transmitted. USE - For base station of cellular communication system using orthogonal frequency division multiplexing (OFDM) technique. ADVANTAGE - The transmission performance is improved. The errors in the transmitted packet data unit are minimized. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) transmitter; and (2) computer program product for packet data transmission. DESCRIPTION OF DRAWING(S) - The figure shows a flow diagram of the packet data transmission process.
