Soft decision decoding has been successfully applied to convolutional and block-coding schemes. This latter suggests some alternative applications with particular attention being paid to transmission codes. Alternate mark inversion (a.m.i.) is used as an example where an effective signal/noise ratio improvement of up to 2.8 dB can be obtained.
