Transmitting device, receiving device, encoder, and encoding method

Abstract

In such a relationship between information transmitted by a primary BCH, for example, and information transmitted by a non-primary BCH as a case of the transmission for a first information sequence that is easy to keep receiving quality and a second information sequence that is difficult to keep receiving quality, a transmitting device and a receiving device are disclosed for making it possible to improve an error rate of the second information sequence. In the devices, an encoder (102) encodes a non-primary BCH information sequence (Sn) with a long code length including a primary BCH information sequence (Sp). On the receiving side, a non-primary BCH information sequence is decoded with a long code length by using the received primary BCH value. With this, a higher encoding gain than encoding only with the non-primary BCH information can be obtained, so that a receiving characteristic of the non-primary BCH can be improved.
