1. A method for increasing a data rate of data available for mobile/handheld (M/H) receivers and for improving quality of channel estimation and equalization in mobile fading for M/H receivers containing a transport data stream, comprising:

  • marking a number of consecutively transmitted transport data packets determined for transmission of data for M/H receivers in a predetermined number of N consecutively transmitted transport data packets in a slot of a transport data stream to designate a portion of the N consecutively transmitted transport data packets for data for M/H receivers, the slot being originally determined for data for M/H receivers and data for stationary receivers and the N consecutively transmitted transport data packets being originally determined for transmission of data for stationary receivers;

    inserting coded data for M/H receivers in the marked transport data packets, wherein the consecutively transmitted transport data packets determined for transmission of data for M/H receivers are inserted symmetrically to a center of the N consecutively transmitted transport data packets and separated from M transport data packets of an actual or a subsequent slot determined for data for M/H receivers by at least one transport data packet; and

    introducing training sequences in segments of data fields of the transport data stream containing marked transport data packets.
