20090161613 | METHOD AND SYSTEM FOR CONSTRUCTING CHANNEL QUALITY INDICATOR TABLES FOR FEEDBACK IN A COMMUNICATION SYSTEM - Aspects of a method and system for constructing channel quality indicator tables for feedback in a communication system are provided. A user terminal may receive a signal transmitted by using a modulation and coding scheme (MCS) from a base station. The user terminal may assess channel quality information by accessing a CQI table to identify a CQI value based on the received radio signal. The CQI table may comprise various modulation regions in terms of spectral efficiency. The identified CQI value may be transmitted to the base station. Various standard system protocols such 3GPP, 3GPP LTE, or WiMAX, may be used for transmissions. The CQI table may be generated via PER versus spectral efficiency and/or SNR, respectively. The base station may select a MCS based on the CQI feedback from the user terminal for transmitting a subsequent radio signal to the user terminal. | 06-25-2009 |
20090232050 | Method And System For Determining Limited Soft Buffer Size On Transport Blocks For Rate Matching - Aspects of a method and system for determining a limited soft buffer size on transport blocks for rate matching are provided. A data stream may be processed for transmission between a base station (eNodeB) and a UE via HARQ procedures. A two-stage rate-matching algorithm may be used in the HARQ procedures. A limited virtual soft buffer size at the UE in the two-stage rate-matching algorithm may be calculated on site based on channel condition information, available channel bandwidth, number of layers in spatial multiplexing, and the capacity of the UE, respectively. The data stream may be first rate-matched to the calculated limited soft buffer size available at the UE, and forwarded for second stage rate-matching to an actual physical channel size determined by the base station. The amount of bits forwarded for second stage rate-matching may equal to the calculated limited virtual soft buffer size of the virtual soft buffer. | 09-17-2009 |
20100023670 | METHOD AND SYSTEM FOR ROUTING DATA IN A PARALLEL TURBO DECODER - Described herein are system(s) and method(s) for routing data in a parallel Turbo decoder. Aspects of the present invention address the need for reducing the physical circuit area, power consumption, and/or latency of parallel Turbo decoders. According to certain aspects of the present invention, address routing-networks may be eliminated, thereby reducing circuit area and power consumption. According to other aspects of the present invention, address generation may be moved from the processors to dedicated address generation modules, thereby decreasing connectivity overhead and latency. | 01-28-2010 |
20130198582 | SUPERCHARGED CODES - A system and method is provided for encoding k input symbols into a longer stream of n output symbols for transmission over an erasure channel such that the original k input symbols can be recovered from a subset of the n output symbols without the need for any retransmission. A symbol is a generic data unit, consisting of one or more bits, that can be, for example, a packet. The system and method utilize a network of erasure codes, including block codes and parallel filter codes to achieve performance very close to the ideal MDS code with low encoding and decoding computational complexity for both small and large encoding block sizes. This network of erasure codes is referred to as a supercharged code. The supercharged code can be used to provide packet-level protection at, for example, the network, application, or transport layers of the Internet protocol suite. | 08-01-2013 |
20130198583 | Systematic Rate-Independent Reed-Solomon Erasure Codes - The present disclosure is directed to a system and method for encoding k input symbols, using a Reed-Solomon erasure correction code, into a longer stream of n output symbols for transmission over an erasure channel. The present disclosure is further directed to a system and method for recovering the original k input symbols from only (and any) k output symbols (out of the n output symbols) received over the erasure channel. A symbol is a generic data unit consisting of one or more bits that can be, for example, a packet. The systems and methods of the present disclosure provide for an adjustable code rate that can be readily adapted based on changing channel conditions without having to reconstruct the encoder/decoder. As a result, such an encoder/decoder can be referred to as rate-independent. | 08-01-2013 |
20150046775 | Encoding and Decoding Schemes to Achieve Standard Compliant Mean Time to False Packet Acceptance - Systems and methods for enabling encoding/decoding schemes that satisfy the IEEE 802.3 Mean Time To False Packet Acceptance (MTTFPA) requirement in an Ethernet Passive Optical Network over Coax (EPoC) are described. The proposed encoding/decoding schemes assume existing Medium Access Control (MAC) layer Cyclic Redundancy Check (CRC) encoding/decoding, thereby requiring no changes in the Ethernet Passive Optical Network (EPON) MAC protocol, but increase error protection in the EPoC physical layer (PHY) to meet the MTTFPA requirement without sacrificing desired Ethernet frame loss ratios and downstream/upstream data rates for EPoC. | 02-12-2015 |
