Abstract
A multi input multi output (MIMO) system for transmitting and receiving packets having a nested preamble format included in said packets and having poly-carrier long training sequence (LTS) and signal field (SIG) for training receivers, in accordance with an embodiment of the present invention. Said packets being transmitted using the modulation scheme of a wireless local area network (WLAN) standard, said nested preamble format for allowing said receivers to use one or more receiver antennas to interpret said LTS and said SIG to increase the efficiency of said MIMO system.
