Patent ID: 8516333

Claim:
A communications network comprising: a user terminal adapted to receive transmissions over a communication link; a gateway in communication with the user terminal and comprising: an adaptive coding and modulation (ACM) module adapted to determine a modulation and coding scheme for data representing content to be communicated to the user terminal, the data including information bits; an encoding module adapted to encode the data as a code block by applying the coding and modulation scheme, the code block including the information bits and parity bits arranged in a first order; a pre-interleaver module adapted to rearrange the code block into a rearranged code block such that the information bits and parity bits are arranged in a second order that is different from the first order; a channel interleaver module adapted to interleave the rearranged code block from the pre-interleaver module; and a modulator module adapted to modulate the information bits and parity bits of the channel interleaved code block as symbols by applying the coding and modulation scheme; and a transceiver module adapted to transmit the symbols to the user terminal over the communication link.
