System and Method for Wireless Communication Using Space-Time Block Code Encoding

摘要

An embodiment provides a method for wireless communications including an access point (AP) space-time block code (STBC) encoding a high efficiency wireless local area network (WLAN) (HEW) signal A (SIGA) fields, and transmitting a preamble comprising a duplicate stream portion including a repeated legacy long training field, and comprising a two-stream portion including the STBC-encoded HEW SIGA fields. In further embodiments, the method includes the duplicate stream portion including a pair of SIG-LTFs (or alternatively a compressed SIG-LTF) which is used for channel estimation and auto-detection.

1. A method for wireless communications by an access point (AP) comprising:
space-time block code (STBC) encoding:
at least one Signal Long Training Field (SIG-LTF) field encoded to facilitate both receiver channel estimation and auto-detection of the remainder of the frame, andat least two high efficiency wireless local area network (HEW) signal (SIG) fields; and transmitting a packet with a preamble comprising a two-stream portion including the STBC-encoded fields.
