Transmission method of orthogonal extension block, receiving method thereof and system thereof

Abstract

The invention relates to a transmission method of an orthogonal extension block, a receiving method thereof and a system thereof. The transmission method comprises the following steps of: confirming a transmission parameter according to a service demand and an usable transmission resource; building the subsidiary channels of physical layers according to the transmission parameter; setting the priority levels of the subsidiary channels of the each physical layer; distributing the jump patterns of extended codes to the subsidiary channels of the each physical layer; modulating the each route of business by means of the data blocks according to the transmission parameter to obtain modulation data blocks; distributing the subsidiary channels of the each physical layer to the each route of the business; extending the modulation data blocks by means of the blocks according to the transmission parameter and the jump patterns to obtain extension data blocks; post processing the extension data blocks by means of base bands; and transmitting the processed extension data blocks. The method and the system can support the building and the flexible configuration of the subsidiary channels of the each physical layer, the multi-priority transmission of multi service, the flexible distribution and dispatching of the resources and multi-cell network deployment, and also can realize an intersymbol diversity effect.
