Patent US8958350 - Systems and methods for high rate OFDM communications - Google Patents
Messages transmitted between a receiver and a transmitter are used to maximize a communication data rate. In particular, a multicarrier modulation system uses messages that are sent from the receiver to the transmitter to exchange one or more sets of optimized communication parameters.

1. A transceiver usable for packet communication comprising:
the receiver decoding the receiver station identifier to determine whether the receiver is an intended recipient of the packet and not decoding a remainder of the packet if the receiver determines it is not an intended recipient of the packet, wherein the receiver receives the packet at a first rate using a first cyclic prefix length and a first pilot tone allocation and receives a message comprising communication parameters which include a second cyclic prefix length and a second pilot tone allocation.
2. The transceiver of claim 1, wherein the receiver is adapted for entering a low power mode if the receiver determines it is not the intended recipient of the packet.
7. The method of claim 6, wherein the receiver is adapted for entering a low power mode if the receiver determines it is, not the intended recipient of the packet.
This application is a Continuation of U.S. application Ser. No. 12/498,184, filed Jul. 6, 2009, now U.S. Pat. No. 8,284,800, which is a Continuation of U.S. application Ser. No. 11/931,791, filed Oct. 31, 2007, now U.S. Pat. No. 7,590,071, which is a divisional of U.S. application Ser. No. 10/382,921, filed Mach 7, 2003, now U.S. Pat. No. 7,522,514, which claims the benefit of and priority under 35 U.S.C. §119(e) to U.S. Patent Application Ser. No. 60/363,218, filed Mar. 8, 2002, entitled “High Rate OFDM Communication System and Method for Wireless LAN,” each of which are incorporated herein by reference in their entirety.
The station 510 detects the ER-enable bit, with the cooperation of the ER detection module, determines this is an ER packet and decodes, with the cooperation of the STA ID de/encoder 650, the RX ST ID bits in the extended header field to determine that the packet is not intended for itself The station 510 then sets the NAV, and related counters, based on the “spoofed” RATE, LENGTH information contained in the SIGNAL Field as discussed below. Since the station 510 knows that this packet is not intended for itself, the station 510 does not even have to decode the packet. An additional benefit of this method is that when this happens, a station can detect very early that it is not the intended recepient of the packet and therefore the station does not need to decode the remainder of the packet. This will save, for example, power in the station since the station will not consume the processing power to decode the remainder of the packet and therefore the station may, for example, go into the low power mode.
Moreover, the disclosed methods can also be readily implemented in software, stored on an information storage media or computer-readable storage medium, such as a hard dirve, memory or optical, magnet or magneto-optic disc, executed on programmed general purpose computer, a special purpose computer, a microprocessor, or the like. In these instances, the systems and methods of this invention can be implemented as program embedded on personal computer such as JAVA® or CGI script, as a resource residing on a server or graphics workstation, as a routine embedded in a dedicated communication system, or the like. The communication system can also be implemented by physically incorporating the system and method into a software and/or hardware system, such as the hardware and software systems of a communications transceiver.
