Abstract: A system, method and device for error detection/estimation in OFDM communications systems is proposed. The disclosed mechanism allows an efficient error prediction in a received packet, without having to perform full FEC decoding of the packet that could impair the overall latency of the system due to the time spent in a complete FEC decoding of the packet. In order to do that, it generates a decision variable with the aim to check whether a received packet has errors or not, after performing only partial FEC decoding of the packet, without either resorting to the use of error-detection codes.

Abstract: In described embodiments, data pattern-based detection of loss of signal (LOS) is employed for a receive path of serializer/deserializer (SerDes) devices. Pattern-based LOS detection allows for detection of data loss over variety of types of connection media, and is generally insensitive to signal attenuation. More specifically, some described embodiments disclose reliable pattern-based detection of LOS across different connection media for incoming receive data when discreet time decision feedback equalization (DFE) is employed.

Abstract: The invention is related to a method of transmitting data from a transmitter to a receiver in particular in a DVB-scenario. Hereby data is transmitted in consecutive bursts and each burst comprises a plurality of Multi-Protocol Encapsulation (MPE) sections and additionally Multi-Protocol Encapsulation - inter-burst-Forward Error Correction (MPE-iFEC) sections and / or Multi-Protocol Encapsulation- Forward Error Correction (MPE-FEC) sections. The content of the transmitted MPE-sections and MPE-iFEC or MPE-FEC sections is mapped into an Application Data Sub-Table (ADST) and an inter-burst-Forward Error Correction Data Sub-Table (iFDST) or Forward Error Correction Data Sub-Table (FDST) respectively. The content of the ADST and iFDST is mapped into ADT's and iFDTS's respectively as far as MPE- and MPE-iFEC sections are concerned. The decoding process is applied on a particular set of ADT and iFDT for MPE- and MPE-iFEC sections and on the ADST and FDST for MPE and MPE-FEC sections and after the decoding was performed on a particular set of ADT and iFDT the data part is copied back into ADST's.
According to the invention the ADT and iFDT or ADST and FDST on which decoding shall be applied is divided into several subblocks before being decoded, each subblock containing one or more lines of the ADT and iFDT or ADST and FDST. Each subblock is then forwarded to the decoder, so that decoding is applied on this subblock, whereby the decoder computes the column status for each subblock, namely the total number of erroneous or missing columns in this subblock and decides whether the content of each subblock can be decoded or not based on the column status of this subblock.Abstract translation: 本发明涉及一种将数据从发射机发送到接收机的方法，特别是在DVB场景中。 由此数据在连续突发中传输，并且每个突发包括多个多协议封装（MPE）部分和附加的多协议封装 - 突发间前向错误校正（MPE-iFEC）部分和/或多协议封装 前向纠错（MPE-FEC）部分。 发送的MPE段和MPE-iFEC或MPE-FEC段的内容被映射到应用数据子表（ADST）和突发间前向纠错数据子表（iFDST）或前向纠错数据 子表（FDST）。 就MPE和MPE-iFEC部分而言，ADST和iFDST的内容分别映射到ADT和iFDTS。 解码过程应用于MPE和MPE-iFEC部分的一组特定的ADT和iFDT以及MPE和MPE-FEC部分的ADST和FDST上，并且在特定的一组ADT和iFDT上执行解码后，数据 部分被复制回ADST中。 根据本发明，在其上解码的ADT和iFDT或ADST和FDST在被解码之前被分成几个子块，每个子块包含ADT和iFDT或ADST和FDST的一行或多行。 然后将每个子块转发给解码器，以便对该子块应用解码，由此解码器计算每个子块的列状态，即该子块中的错误或缺失列的总数，并决定每个子块的内容是否可以 根据这个子块的列状态来解码还是不解码。
