<P>PROBLEM TO BE SOLVED: To improve communication quality by estimating the biasing of the quality of reception at each position within a frame. <P>SOLUTION: In communication from a transmission station to a reception station, quality of reception is estimated for each data position within a data frame being received in the receiving station, thus grasping different reception quality conditions for each position, being generated due to various kinds of characteristic deterioration factors in a process until data to be communicated are received by the reception station through a transmission line, after being transmitted from the transmission station and hence supplying the estimation result to a data-processing section at a later stage for utilization. Additionally, the estimation result is notified to the transmission station side, and the arrangement of transmission data is reconstructed at the side of the transmission station. Additionally, the arrangement method of the transmission data is changed appropriately, according to the degree of importance in data to be communicated. Further, the transmission data rearranged are restored appropriately on the side of the reception station to obtain reception data, and the quality of the communication service is improved. <P>COPYRIGHT: (C)2004,JPO |
