Abstract

The method includes steps: comparison step determines that the input signal belongs to which segmentation function; addressing parameter database of segmentation function so as to obtain specific parameters of segmentation function; calculating segmentation function generates not equal compressed data. The equipment includes following devices: comparator in use for determining that the input signal belongs to which segmentation function; database of segmentation function in use for obtaining specific parameters through addressing step; calculation unit in use for generating not equal compressed data. The invention carries out not equal compression and expansion for the input signal of encoder for Turbo codes and external additional information. The invention saves consumption of storage resources of encoder for Turbo codes without reducing performance of Turbo decoder basically.

Description

technical field

[0001] The invention relates to a method and device for saving storage resources of a Turbo code decoder, which are applied to a communication system or a wireless communication system, especially in a Code-Division Multiple Access (CDMA) system. Background technique

[0002] Channel encoding and decoding technology has a relatively independent position in the entire mobile communication system, and is one of its key technologies, which determines the performance of the mobile communication system. Channel encoding and decoding are mainly to reduce the signal propagation power and solve the inevitable fading problem of the signal in the wireless propagation environment. The use of encoding and decoding technology combined with interleaving technology can reduce the bit error rate performance. Compared with the case without encoding, the traditional convolutional code can reduce the bit error rate by two orders of magnitude to 10 -3 ~10 -4 , and the Turbo co...
