Abstract:
PCT No. PCT/GB95/02892 Sec. 371 Date Jul. 21, 1997 Sec. 102(e) Date Jul. 21, 1997 PCT Filed Dec. 12, 1995 PCT Pub. No. WO96/19054 PCT Pub. Date Jun. 20, 1996Data are coded with a first error correcting code to produce first coded bits. Control data are coded using a heavily redundant second error corrected code and added modulo 2 to the first coded bits. Decoding is performed by ascertaining which valid codeword of the second code (when added to the received codeword) gives the lowest error count when the resultant is decoded according to the first code.
