1. A wireless transceiver device employing a code select code division multiple access method, comprising:
- a serial-parallel converter configured to divide (k*q+n) bits data into k*q sets of bit series and n sets of beat groups;
an encoder configured to execute error correction coding on the bit series and output n pieces of parity series, each parity series having q bits data;
n pieces of code selectors configured to select a orthogonal code corresponding to the data subjected to the each parity series; and
n pieces of spreaders configured to diffuse the each orthogonal code by using one bit of the beat groups and to output a diffused data,wherein the serial-parallel converter is configured to rearrange the (k*q+n) bits data with a serial format and output the (k*q+n) bits data as parallel format data.

Abstract
A wireless transceiver device employing the code select code division multiple access method includes an encoder configured to execute error correction coding on data having a predetermined number of bits among data inputted from outside, and a code selector configured to select a code corresponding to the data subjected to correction coding. The wireless transceiver device performs wireless communication by use of the data inputted from the outside excluding the data having the predetermined number of bits and by use of the code.

3. A wireless communication method employing the code select code division multiple access method, comprising the steps of:
-
searching for a code having the highest correlation with a piece of received data; outputting soft decision data corresponding to the code; executing error correction of the soft decision data and outputting the data as decoded data; executing error correction coding on the decoded data and outputting the data as correction parity data; and outputting a decoded beat by use of the received data, the decoded data, and the correction parity data.
