description	The invention relates to the field of wireless communication, in particular to a hybrid error retransmission (HARQ) integrated merging decoding method based on LDPC (Low Density Parity Check) codes in wireless communication. Comprising the following steps of: 1, cascading parts which are received for the first time in a received signal to form a complete non-repeated receiving vector, and then sequentially connecting overlapped receiving parts behind the receiving vector according to positions in an original code word; 2, constructing an extended check matrix for the structure of the received vector processed in the step 1; and step 3, performing LDPC decoding by using the extended check matrix and the extended vector, and judging whether decoding succeeds or not according to a decoding result. By adopting the integrated merging decoding scheme provided by the invention, the decoding performance can be effectively improved, that is, correct decoding can be realized under a lower signal-to-noise ratio.
