Abstract : Block codes have not obtained the error correction capabilities as originally predicted since most error bits are highly correlated to adjacent bits; therefore, errors have a tendency to occur as bursts rather than random errors. The interleaving concept makes these bursts appear as random errors; hence, the errors can be corrected by block codes. Data collected over an ionospheric path from Davis, California, to Deal, New Jersey, was used with computer simulation to determine an optimum interleaver size and an optimum block code that could be used for this particular path.
