<??>Code words such as doubly-encoded Reed-Solomon code comprise first code blocks including a plurality of information words arranged in a first arrangement and a plurality of first check words generated by a code having a Hamming distance of d1 to said information words, and second code blocks including a plurality of information words arranged in a second arrangement and a plurality of first check words each having a plurality of information words and a plurality of first check words belonging to different one of said first blocks, and a plurality of second check words generated by a code having a Hamming distance of d2 to said plurality of information words and said plurality of first check words, are decoded to correct errors. For such a doubly-encoded error correction code, at least error detection is effected in a first decoding and flags indicating decoding conditions are added. In a second decoding, error detection for the first code blocks and error correction for S2 words at unknown locations and E flagged word erasure, where S2 and E satisfy a relation of 2S2 + E </= d1 - 1, are parallelly or sequestially are effected, and a combination of S2 and E having a high correction capability and a low probability of mis-correction is selected from a plurality of correction results of error locations and the number of flags added at the first decoding, and the word errors are corrected based on the selected combination.

Title: Ground speed sensor
IPC: G01S15/60
Filed: 1985-05-13
Granted: 1990-11-07
Abstract: The sensor comprises an ultrasonic transmitter and receiver and a processing circuit in which a phase-locked loop tracks the received frequency in order to indicate the speed of a vehicle over the ground. A circuit (18) provides an attenuated and phase-shifted replica of the transmitted signal. This is combined in a circuit (20) with the received signal (14) to cancel out a cross-talk component in the received signal. A low pass filter (26) and squaring circuit (28) provide a signal (30) for the phase locked loop which is substantially pure at the reflected and received signal frequency. It is therefore possible to compare this with a reference frequency corresponding to zero speed to provide an output signal with sign and magnitude indicating respectively the direction (forwards or reverse) and speed of movement of the vehicle.
