RT Journal Article ID 07fbf7586b90129b A1 Pimenov, V. A. T1 Analysis of Efficiency of the Noise-Immunity Encoding in Channels with Discrete Frequency-Aggregate Signals JF Telecommunications and Radio Engineering JO TRE YR 2005 FD 1006-02-03 VO 63 IS 2-6 SP 547 OP 554 AB Analysis of efficiency of noise immunity coding in channels with discrete frequency-aggregate signals is carried out. It is shown that there exists a possibility to increase efficiency for noise immunity coding in channels with multiple-position signals. Here, presentation of such systems on the basis of cascade codes is a productive tool.
