摘要： A method for generating a preamble of a frame for a multiple input multiple output (MIMO) wireless communication begins by, for each transmit antenna, generating a carrier detect field. The method continues by, for a first grouping of the transmit antennas, generating a first guard interval following the carrier detect field; and generating at least one channel sounding field. Continuing, the method applies cyclical shift prior to transmission via the first grouping of the transmit antennas. When the MIMO wireless communication includes more than the first grouping of the transmit antennas, for another grouping of the transmit antennas. For the another grouping of the transmit antennas, generating at least one other channel sounding field. The method proceeds by generating the first guard interval prior to the at least one other channel sounding field, and applying another cyclical shift prior to transmission via the another grouping of the transmit antennas.

摘要： A method and system for antenna selection diversity with dynamic gain control. A receiver selects a starting antenna and dwells on it until an incoming signal is detected. An AGC is applied on the received signal and an estimate of the received power is determined for the starting antenna. The receiver may dwell on other antennas if the signal in the first antenna is not strong enough for signal processing. The gain of an antenna may be set by the gain and power levels of the previously dwelled-on antennas and/or by a power coupling factor that exists between the antennas in an antenna switch. The receiver switches through the remaining antennas as long as necessary to select at least one of the antennas for signal processing. Dynamically adjusting the gain of antennas in a diversity system provides a more accurate and efficient antenna selection scheme.
摘要翻译：一种采用动态增益控制的天线选择分集方法和系统。接收机选择起始天线并驻留在其上，直到检测到输入信号。对接收的信号应用AGC，并且为起始天线确定接收功率的估计。如果第一天线中的信号不足以用于信号处理，则接收机可以驻留在其他天线上。天线的增益可以由先前驻留的天线的增益和功率电平和/或由天线开关中的天线之间存在的功率耦合因子来设定。只要需要选择至少一个天线进行信号处理，接收机就切换剩余的天线。在分集系统中动态地调整天线的增益提供了更精确和更有效的天线选择方案。

摘要： A method for multiple protocol wireless communications begins by determining protocols of wireless communication devices within a proximal region. The method then continues by determining whether the protocols of the wireless communication devices within the proximal region are of a like protocol. The method continues by, when the protocols of the wireless communication devices within the proximal region are not of a like protocol, selecting a protocol of the protocols of the wireless communication devices within the proximal region based on a protocol ordering to produce a selected protocol. The method continues by utilizing the selected protocol by the wireless communication devices within the proximal region to set up a wireless communication within the proximal region.
