20080276151 | METHOD AND APPARATUS FOR DECODING A LDPC CODE - In a decoder for decoding a low density parity check (LDPC) code suitable for decoding multi-rated LDPC codes, a method is provided. The method comprises the steps of: providing a memory for the decoding with the memory dependent on a parity check matrix H with maximum number of “1”s; using a number of column updating units, updating columns parallely and simultaneously producing messages; and using a number of row updating units, updating rows parallely and simultaneously producing messages. Whereby an improved architecture in a logic and the memory is provided such that an improved throughput, power consumption, and memory area is achieved. | 11-06-2008 |
20080304403 | METHOD AND SYSTEM FOR DIVERSITY RECEIVER BASED ON TDS-OFDM TECHNOLOGY - A method for selecting parameter comprising the steps of: providing a plurality of paths each path associated with an independent antenna, and each path comprising: a set of parameters associated with a particular channel; and deriving a parameter among each and every of the set of parameters associated with a particular channel. The method further comprises the step of providing a time de-interleaver or FEC decoder shared by the plurality of paths. | 12-11-2008 |
20080304592 | METHOD AND SYSTEM FOR DIVERSITY RECEIVER BASED ON TDS-OFDM TECHNOLOGY - A method and apparatus for a receiver comprises: a plurality of paths with each path associated with an independent antenna. Each path comprises: a channel estimation device associated with a particular channel; and a set of parameters denoting channel characteristic associated with each path. The receiver further comprises a time de-interleaver or FEC decoder shared by the plurality of paths. Whereby at least one device that use significant amount of memory is shared by the plurality of paths. | 12-11-2008 |
20090016454 | TIME DE-INTERLEAVER IMPLEMENTATION USING AN EMBEDDED DRAM IN A TDS-OFDM REC - A receiver having a de-interleaver with a processor for processing interleaved data; and a built-in eDRAM coupled to the processor for processing the interleaved data is provided. | 01-15-2009 |
20090070659 | LDPC DECODER WITH AN IMPROVED LLR UPDATE METHOD USING A SET OF RELATIVE VALUES FREE FROM A SHIFTING ACTION - In a decoder having an improved LLR (log-likelihood-ratio) update method is provided. The method comprising the steps of: providing a parity check matrix; and using merely a set of parameters on a row of the parity check matrix instead of data of the whole non-zero elements of the parity check matrix free from at least one shifting action after each row updating; thereby saving memory space and process time. | 03-12-2009 |
20090222712 | DECODING SCHEME FOR CORRECTING BOTH ERASURES AND ERRORS OF REED-SOLOMON CODES IN A DIGITAL COMMUNICATION SYSTEM - A method for correcting both erasures and errors of Reed-Solomon codes in a digital communication system is provided. The method comprises the steps of: calculating a syndrome; calculating a set of erasure locations; replacing errata evaluator polynomial by a function having a difference value; and replacing errata locator polynomial by a function having the difference value. | 09-03-2009 |
20100027614 | ERROR AWARENESS AND MEANS FOR REMEDYING SAME IN VIDEO DECODING - A DTV receiver having method using elastic decoding method is provided. The method comprises the steps of: receiving a signal for processing; decoding the signal using a source decoder; determining a portion of the signal that are problematic; and using elastic decoding to remedy the portion of the signal that are problematic. | 02-04-2010 |
