摘要： A method and a system for data transmission are provided. The method includes: determining a size of a first block and a first degree distribution for a first data transmission according to a parameter which is related to a hardware specification of a receiving node; determining a channel loss rate of a channel between a sending note and the receiving node when completing the first data transmission; determining a size of a second block and a second degree distribution for a second data transmission according to the channel loss rate; and performing, by the sending node and the receiving node, the second data transmission according to the size of the second block and the second degree distribution.

摘要： A method and apparatus for decoding a coded data stream of bits using an inner decoder, deinterleaver and an outer decoder. The outer decoder first decodes by error correction decoding for r errors per word. The decoding is terminated and a decoded word is outputted if the syndromes of the corrected word of the first decoding are all zeros. If the syndromes of the corrected word of the first decoding are not all zeros, a second decoding is performed by error decoding and erasure for the number of errors reduced by one and the number of erasures increased to two. The decoding is terminated and a decoded word is outputted if the syndromes of the corrected word of the second decoding are all zeros. If the syndromes of the corrected word of the second decoding are not all zeros, the second decoding by correcting and erasure decoding is repeated for the number of errors reduced by one and the number of erasures increased by two for each iteration of the second decoding.

摘要： A method for autonomous mower navigation includes receiving a return-to-zero encoded signal including a pseudo-random sequence, transforming the received signal to a non-return-to-zero representation, digitally sampling the non-return-to-zero signal representation in a time domain, filtering the sampled signal utilizing a reference data array based on the return-to-zero encoded signal to produce a filter output, and determining a location of the autonomous mower relative to a defined work area based on an evaluation of the filter output.
