Abstract  Abstract

In transmission in which MIMO is applied there have been problems that the number of variable parameters increases and the number of information bits necessary for control channel increases. When the number of simultaneous multiplex users in one frame increases there is also a problem of increased control channel information in proportion to the number of users. Error correction coding is performed for the control channel information based on the Adaptive Modulation and Coding scheme and the above error correction coded control channel information is transmitted after being modulated with a predetermined modulation scheme and further according to propagation condition the coding rate in the above error correction coding is made variable.
