Abstract :
This paper proposes a class of raptor-like rate compatible low-density parity check (LDPC) codes for the cloud transmission (CTxN) system. The proposed LDPC codes have lengths of 16,200 and 64,800 which are the same as those of DVB T2/S2 LDPC codes so that the CTxn system can easily be combined with the DVB-T2/S2 system for a second layer service. As the proposed LDPC codes are optimized at low coding rate range (R <;1/2), their performance is not only close to the Shannon limit, but also better than the DVB-T2/S2 LDPC codes. Moreover, the proposed LDPC codes have raptor code´s property so that they can be decoded with a punctured codeword at the receiver for power saving and less latency under high signal-to-noise ratio regions.
