ROBUST SYMBOL TRANSMISSION AND RECEPTION METHOD USING HIERARCHICAL MODULATION IN WIRELESS ACCESS SYSTEM

摘要

The present invention provides for being sent and received in hierarchical modulation method robust symbol wireless access system and equipment support it is identical. In wireless access system, the method for one embodiment according to the invention includes the following steps: to generate the first symbol transmitting layered modulation (HM) symbol of one kind; Generate the second symbol; HM symbols are generated in conjunction with first symbol and the second symbol; HM sends symbol, wherein the first symbol, can be generated through spatial reuse (SM) technology, the technology or Space-Time Codes and the second symbol of Wave beam forming can be generated through spatial reuse (SM) technology, the technology or Space-Time Codes of Wave beam forming.
