摘要
The present invention is space-time block coding: relates to a channel estimation scheme and a cyclic prefix of the regeneration apparatus and method in an orthogonal frequency multiplexing scheme in a mobile communication system using the (STBC Space-Time Block Code). To this end, we propose a channel estimation method in the present invention of the embodiment, the channel impulse response length than in an orthogonal frequency multiplexing scheme, the mobile communication system or an orthogonal frequency multiplexing scheme does not transmit the cyclic prefix of transmitting a short cyclic prefix mobile communication system . And it proposes a process of removing the tail and circulation recovery process cyclic prefix re-creation method through the space-time block coding scheme in the movement of the orthogonal frequency multiplexing method using the communication system. Meanwhile, in the present invention have proposed a cyclic prefix as the regeneration method, it will consider the ways to minimize the complexity of the receiver at the same time. Finally, we propose a technique to combine the cyclic prefix scheme to regenerate the channel estimation method proposed by the embodiment of the present invention to propose the present invention.
