Embodiment Construction

[0020] The receiver decoding method of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, as figure 1 as shown, figure 1 It is a flow chart of the receiver decoding method of an embodiment, including the following steps:

[0021] Step S1: Calculate the address of each filling bit in the received code block according to the communication protocol used by the transmitter;

[0022] Step S2: Backfilling the filling bits at the corresponding positions in the code block according to the address of the filling bits;

[0023] Step S3: Decoding the code block after the backfill processing.

[0024] Wherein, the stuffing bits backfilled include hard bits or soft bits; when hard bits are used, it is determined directly according to the communication protocol used by the transmitter; when soft bits are used, the specific stuffing bits are determined according to the protocol used by the transmitter ( hard bits), and th...

Abstract

The invention provides a receiver decoding method which comprises the following steps of: calculating an address of each filling bit in the received code block according to a communication protocol used by an emitter; filling the filling bite on the corresponding position in the code block according to the address of the filling bit; and decoding the filled code block. The invention also provides a receiver decoding device. According to the technology of the invention, the error filling bit is avoided being input to the decoder for decoding, thus the problem that the whole transmission block is discarded or retransmitted due to decoding failure caused by error of the filling bit is thoroughly solved, the decoding efficiency and the throughput of a receiver are increased, and the bit error rate of decoded data is lowered.

Description

technical field [0001] The invention relates to a receiver decoding method and device, belonging to the technical field of mobile communication. Background technique [0002] For mobile communication systems, such as WCDMA, TD SCDMA, and LTE, both transmitter encoding and receiver decoding are required during baseband data processing, and the decoding performance and efficiency of the receiver are particularly important. [0003] In the encoding process of the transmitter, the multiple code blocks formed after the transmission block is divided, and the value of each code block has a fixed size. It is possible that the length of the data to be encoded does not match the size of the code block. A part of stuffing bits are filled in the data, so that the length of the stuffed data matches the size of the code block. However, since some bit transmission errors will inevitably occur during the wireless transmission of the code block, and any bit (including padding bits) error in...
