Some new outlooks on burst error correcting capabilities of Reed-Solomon codes with applications in mobile communications

摘要

Some hounds on the required number of parity check symbols for burst error correction are discussed. Equations determining burst error correction capabilities of Reed-Solomon (RS) codes Constructed over Galois fields of characteristic two arepresented. Tables providing burst error Correction Capabilities of RS Codes Constructed over GF(256) and GF(64) are provided. Some applications of RS codes in mobile communications are Covered, in particular the selection of the (63, 47) Rs codes for CDPD networks is explained. One legitimate concern regarding the application of RS codes in mobile communications is the computational complexity of the RS codes standard decoding method. Three alternative decoding techniques, suitable for RS codes with lowerror correcting capability are described.
