Abstract

The invention discloses signal decoding methods, a communication terminal and a device with a storage function. A signal decoding method comprises the steps of receiving a coding signal, wherein the coding signal comprises at least one subsignal; carrying out odd times of sampling on at least partial subsignals in the coding signal, and obtaining a first digital signal corresponding to the codingsignal according to a sampling result, wherein an odd number is greater than 1; and decoding the first digital signal, thereby obtaining an original signal. In the mode, according to the method, the communication terminal and the device, a decoding bit error rate can be reduced.

Description

technical field [0001] The invention relates to the communication field, in particular to a signal decoding method, a communication terminal and a device with storage function. Background technique [0002] For signals encoded by 4PPM (pulse-phase modulation, pulse position modulation) scheme, the general decoding method is to select the level of the middle point of each small pulse of the received signal as the level of this small pulse, and send it to the subsequent decoding module for decoding. [0003] In the process of actually realizing 4PPM decoding, the applicant of the present application found that when using a non-specialized infrared transceiver chip, due to environmental interference, the signal received by the receiving end is not particularly ideal (such as glitches and insufficient pulse width), the original The scheme will have a large bit error rate. Contents of the invention [0004] The technical problem mainly solved by the present invention is to pro...
