| 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 ... |
