MITIGATING INTERCARRIER AND INTERSYMBOL INTERFERENCE IN ASYNCHRONOUS WIRELESS COMMUNICATIONS

机译:异步无线通信中的载波间干扰和符号间干扰

摘要

Systems and methodologies are described that facilitate mitigating intercarrier and intersymbol interference in symbol transmissions over wireless communications where transmitter and receiver may not be time synchronized. Symbol periods can be extended for transmitting symbols such that an original symbol can be transmitted with one or more duplicated symbols keeping phase continuous, blank symbols, and/or the like. In this regard, multiple receiver windows can be required to receive the symbol such that at least one window has a non-interfered symbol even though timing can be misaligned (e.g., in asynchronous communications channels).
