Design and performance evaluation of concatenated coding for future DVB-S systems
It is imperative to maximize bandwidth efficiency and achieve low probabilities of bit errors
over satellite channels which suffer large noise effect. Digital Video Broadcasting (DVB)
describes a new coding and modulation schemes based on LDPC codes concatenated with
BCH codes allowing a quasi-error free operation at about 0.7 dB to 1.0 dB close to
Shannon’ s limit that permits greater flexibility and more efficient use of bandwidth
capacity without significant increase of system complexity. This research intends to test the …
