Since for ML decoding it is very easy to construct codes with good thresholds and low error floors, this gives- - an entirely new way of constructing codes.Urbanke, RuedigerIEEEUrbanke,Ruediger."What is new in coding and how this might impact optical communications,".Optical Communication (ECOC...
arriving at the receive end may be erroneous. Channel coding is introduced to restore information to the maximum extent at the receive end, thereby reducing the bit error rate. WLAN uses two channel coding schemes: Binary Convolutional Encoding (BCC) and Low Density Parity Check (LDPC). ...
Hamming code is not used in modern data transmission. Wired data connections are generally not noisy enough to warrant the overhead of added parity data, and if an error is encountered, it may be faster to ask the sender to retransmit the faulty packet. Also, low-density parity-check (LDP...
However, unless your money is from inheritance or lottery, you cannot become poor by indulgence. Because you might try to be indulging one time and alarm of yourself gets off that you are wasting money. The only way to become poor from rich is bad investment. The same thing to time. We...
data channels. LDPC codes are considered highly efficient and are deployed for both wired and wireless communication. In fact, LDPC is now part of the DOCSIS 3.1 specification, which has helped to improve its overall performance. LDPC uses a low-density parity-check matrix to describe the code...
Original 802.11 standards provide MCS coding for each MIMO combination, which is abandoned by 802.11ac. Therefore, there are only 10 MCS coding modes in 802.11ac. A higher MCS value indicates higher maximum throughput. This is because different modulation coding modes use different numbers of bits...
another FEC technique to improve net coding gain performance. Traditional hard decision FEC communication systems compared an incoming bit to a fixed threshold level. Anything that fell above this hard threshold is defined as a “1” bit and anything below the threshold is set to a “0” bit....
UL-SCH stands for uplink shared channel and is a transport channel, which performs CRC addition, code block segmentation, channel coding, and rate-matching on the input transport block. The outcome of the UL-SCH is the coded and rate-matched bits of input ...
aChapter 14 thus gives an overview of the different coding schemes that are most popular for wireless communications, including the near-optimum turbo codes and Low Density Parity Check (LDPC) codes that have drawn great attention since the early 1990s. 第14章因而给为无线通信是最普遍的,包括近最...
