PCT No. PCT/GB96/02423 Sec. 371 Date Mar. 12, 1998 Sec. 102(e) Date Mar. 12, 1998 PCT Filed Oct. 3, 1996 PCT Pub. No. WO97/14235 PCT Pub. Date Apr. 17, 1997Received signals are processed to generate bit confidence measure signal values. Before these are forwarded to a soft decision decoder, correction factors are applied, e.g., by a look-up table, to reduce the extent to which the signal statistics differ from a logarithmic representation of the error statistics of the received signals. Alternatively, or as well, the bit confidence measure signal values may be summed and thresholded to provide a quality-indicating signal.
