Abstract
An apparatus for and method of correcting errors in a received signal comprised of a rate-one orthogonal convolutional code generated by an LFSR involved feeding (403) a received signal into a multiple-stage shift register (201). Estimates of one of the stages of the shift register are performed by estimators (203, 205, 207, 209, 211, 213, and 215) and are based on the outputs of several of the other stages of the shift register (201). These estimates are combined on a bit-by-bit basis to provide a corrected received signal, which is used as the output of the shift register (201).
