Reception method and reception device estimating reception quality and communication system using the reception device

摘要

Variation in received signal qualities at positions in a frame is estimated so as to improve a communication quality. In communication from a transmitting station to a receiving station, a received signal quality is estimated per data position in a data frame received by the receiving station, thus to grasp situations of the received signal quality varied depending on a position which is caused by various factors of property deterioration in a process from transmitting communication data from the transmitting station to receiving it by the receiving station via a transmission path. Further, an estimating result is supplied to a data processing unit and used at a latter stage. The estimating result is notified to the transmitting station and arrangement of transmitting data is reconstructed on the transmitting station side. The arrangement of the transmitting data is properly changed in accordance with importance of the communication data. Further, the rearranged transmitting data is properly restored on the receiving station side, thereby obtaining received data and improving a quality of a communication service.

主权项

1. A receiving method comprising:
receiving a signal modulated by a multivalue modulating method as a received signal, the received signal including a plurality of bit sets, each of the bit sets including a plurality of bits arranged in respective ordered bit positions within each of the bit sets, identifying one of the respective bit positions in each of the plurality of bits sets based on the ordered bit positions within each of the plurality of bit sets, determining, for the identified one of the respective bit positions within each of the plurality of bit sets, a respective parameter indicating a received signal quality per bit position, averaging the respective parameter indicating the received signal quality per bit position for the one of the identified bit positions over the plurality of bit sets to obtain an average parameter, processing, by a processing unit, received data by use of said average parameter.
