Cancelling interference by determining modulation and coding information embedded in a received spatial stream
Abstract:
Data-directed interference cancellation involves detecting the modulation and coding embedded in an interfering spatial stream and using the detected modulation and coding for interference cancellation in conjunction with decoding another spatial stream. In an 802.11ac-based system, the modulation and coding scheme of a spatial stream is specified by a SIGB value. Upon detecting the SIGB value of an interfering spatial stream in a received signal, the modulation and coding indicated by the SIGB value is used to identify the information transmitted in the interfering spatial stream. Once this information is known, the interference caused by the transmission of this information is canceled from the received signal to improve the decoding of the other spatial stream (or streams) in the received signal.
