| 20110258521 | INTERLEAVING SCHEME FOR AN LDPC CODED QPSK/8PSK SYSTEM - An approach is provided for interleaving low density parity check (LDPC) encoded bits in QPSK/8PSK modulation systems. By assigning the bits determining modulation symbols based on different bit degrees, one can efficiently find the desirable tradeoff between error performance and error floor provided by the LDPC codes in use. | 10-20-2011 |
| 20110202814 | INTERLEAVING SCHEME FOR AN LDPC CODED 32 APSK SYSTEM - An approach is provided for interleaving low density parity check (LDPC) encoded bits in 32APSK modulation systems. By assigning the bits determining modulation symbols based on different bit degrees, one can efficiently find the desirable tradeoff between error performance and error floor provided by the LDPC codes in use. | 08-18-2011 |
| 20110173509 | BIT MAPPING SCHEME FOR AN LDPC CODED 16APSK SYSTEM - A digital communication system, having a transmitter to transmit a digital signal; and a receiver to receive the digital signal; wherein the digital signal utilizes a 16APSK system, and the signal is bit-mapped using gray mapping, and bits of the digital signal are ordered based on the values of a log likelihood ratio from a communications channel. | 07-14-2011 |
| 20110096718 | EFFICIENT FRAME STRUCTURE FOR DIGITAL SATELLITE COMMUNICATION - A digital communications system and method to transmit and receive a digital communications signal wherein the digital signal has a plurality of frames, wherein at least two modulations are supported, and wherein each of the plurality of frames has the same number of symbols. | 04-28-2011 |
| 20100316144 | EFFICIENT FRAMING SCHEMES FOR SUPPORTING VCM/ACM IN DIGITAL SATELLITE TRANSMISSION SYSTEMS - A digital communication system and method using a digital signal having a plurality of frames to transmit data, including a first frame and a second frame, wherein each of the plurality of frames has a frame structure; and wherein the first frame has, a plurality of codewords comprising user data, and a Next Frame Composition Table to set the structure for the second frame, and wherein the second frame has at least one codeword. | 12-16-2010 |
