Abstract

There is provided a communication device capable of performing encoding and decoding calculation processing according to a parameter necessary for encoding and decoding processes, the processing load of which is thereby reduced, so that a small size and a low power consumption are achieved. The process steps of CRC addition for adding a CRC code (S1), transport block coupling and code block dividing (S2), and channel encoding (S3) are performed. After that, the above parameter that does not change during communication is fixed and a composite function Z(x) combining a process based on a parameter that changes during communication is applied to perform encoding, thereby generating wireless transmission data (S4 to S12).

Description

technical field [0001] The present invention relates to a communication device, in particular to a communication device capable of realizing an encoding / decoding algorithm suitable for a wireless communication system. Background technique [0002] Conventional communication devices (base stations and mobile stations) used in mobile communication will be described. [0003] The base station not only communicates with the mobile station, but also sends and receives signals with a higher-level device. For example, a base station that receives data from a high-level device terminates the protocol of the interface in the interface unit, and extracts desired data from the received data. [0004] The extracted data is coded and modulated, its radio frequency is up-converted (up-converted frequency), and transmitted as a radio signal from the antenna. [0005] On the other hand, in the mobile station that has received the wireless signal transmitted from the above-mentioned antenn...
