source symbol造句
例句与造句
- A fountain code is optimal if the original " k " source symbols can be recovered from any " k " encoding symbols.
- The algorithm derives this table from the estimated probability or frequency of occurrence ( " weight " ) for each possible value of the source symbol.
- The output from Huffman's algorithm can be viewed as a variable-length code table for encoding a source symbol ( such as a character in a file ).
- Adapting the algorithm to use an additional array to store the shape of the region allows generalization to cover " fuzzy " flood filling, where an element can differ by up to a specified threshold from the source symbol.
- Using a fixed-rate erasure code, a receiver missing a source symbol ( due to a transmission error ) faces the coupon collector's problem : it must successfully receive an encoding symbol which it does not already have.
- It's difficult to find source symbol in a sentence. 用source symbol造句挺难的
- Furthermore, for engineering purposes such as synchronization and monitoring, it is desirable to get reasonable good estimates of the received source symbols without going through the lengthy decoding process which may be carried out at a remote site at a later time.
- This code is able to recover a source block from any set of encoded symbols equal to the number of source symbols in the source block with high probability, and in rare cases from slightly more than the number of source symbols in the source block.
- This code is able to recover a source block from any set of encoded symbols equal to the number of source symbols in the source block with high probability, and in rare cases from slightly more than the number of source symbols in the source block.
- By an AEP-related argument, given a channel, length n strings of source symbols X _ 1 ^ { n }, and length n strings of channel outputs Y _ 1 ^ { n }, we can define a " jointly typical set " by the following:
- Fountain codes are known that have efficient encoding and decoding algorithms and that allow the recovery of the original " k " source symbols from any " k " of the encoding symbols with high probability, where " k " is just slightly larger than " k ".
- A more advanced Raptor code with greater flexibility and improved reception overhead, called RaptorQ, has been introduced into the IETF . This code can be used with up to 56, 403 source symbols in a source block, and a total of up to 16, 777, 216 encoded symbols generated for a source block.
- Using terms from formal language theory, the precise mathematical definition is as follows : Let S and T be two finite sets, called the source and target homomorphism of S ^ * into T ^ *, which naturally maps each sequence of source symbols to a sequence of target symbols, is referred to as its "'extension " '.

- Systematic codes have the advantage that the parity data can simply be appended to the source block, and receivers do not need to recover the original source symbols if received correctly & ndash; this is useful for example if error-correction coding is combined with a hash function for quickly determining the correctness of the received source symbols, or in cases where errors occur in erasures and a received symbol is thus always correct.
