Document Type and Number:
Japanese Patent JP4447036
Kind Code:
B2
Abstract:
In variable rate data transmission, a data transmission method or the like is provided which enables adjustment for achieving desired erroneous rate detection. A transmitting side places a calculated error detecting code after the transmission data in each frame, generates frame data in which an R-bit series before the final bit position of the error detecting code is rearranged in inverse order, and transmits. A receiving side assumes the transmission data and error detecting code by assuming the final bit position of the frame data in each frame, conducting the assumption presuming that the rearrangement in inverse order has occurred on the transmitting side. Among the assumed final bit positions, the position determined to be errorless as a result of the error detection based on the assumed transmission data and error detecting code is determined as the final bit position. R can be greater or less than the number of bits of the error detecting code.
