FREQUENCY SPREADING FOR HIGH-PERFORMANCE COMMUNICATIONS

摘要

Methods and systems are provided for using frequency spreading during communications, in particular communications in which multiple carriers (or subcarriers) are used. The frequency spreading may comprise generating a plurality of spreading data vectors based on transmit data, such as by application of a spreading matrix to portions of the transmit data. Each spreading data vector may comprise a plurality of elements, for assignment to the multiple subcarriers. The receive-side device may then apply frequency de-spreading, to obtain the original transmit data. The frequency de-spreading may comprise use of the same spreading matrix on data extracted from received signals, which (the data) may correspond to the plurality of spreading data vectors.
