摘要： A method of performing dynamic sounding in a wireless communication device includes determining whether to perform sounding based on an age of current channel state information (CSI). An achievable throughput can be recorded as a reference throughput after performing the sounding. A current achievable throughput can be compared with the reference throughput. A CSI timestamp can be reset when the current throughput is above the reference throughput by a first predetermined amount, thereby prolonging a lifespan of the current CSI. The CSI timestamp can be reduced when the current throughput is below the reference throughput by a second predetermined amount, thereby reducing the lifespan of the current CSI.

摘要： A hybrid device can execute hybrid ARP functionality to manage one-to-many associations between a single network layer address and multiple link layer addresses of other hybrid devices. In accordance with the hybrid ARP functionality, the hybrid device can determine a transmission route, a corresponding one of a plurality of network interfaces of a destination hybrid device, and a corresponding one of a plurality of link layer addresses of the destination hybrid device, based on address resolution store entries associated with the destination hybrid device. The identified link layer address can be populated in a frame for transmission to the destination hybrid device. Additionally, the hybrid ARP functionality can be configured to operate in conjunction with conventional ARP functionality implemented by upper protocol layers. The hybrid ARP functionality can serve as a “proxy” between the conventional ARP functionality and one or more hybrid devices of the hybrid communication network.

摘要： A network based positioning (NBP) system is disclosed that allows any of its access points (APs) to initiate ranging operations with a station device (STA), regardless of whether the STA is in power save mode and regardless of whether a particular AP is currently associated with the STA. For example, to initiate ranging operations with the STA from a non-associated AP, the non-associated AP obtains the TSF timer of the associated AP, and then uses the obtained TSF timer to derive the associated AP's beacon transmission schedule and thereby determine when the STA's corresponding wake-up periods occur. Thereafter, the non-associated AP can initiate ranging operations with the STA during the STA wake-up periods, thereby ensuring that probes sent from the non-associated AP will arrive at the STA while the STA is awake from power save mode.
摘要翻译：公开了一种基于网络的定位（NBP）系统，其允许其任何接入点（AP）与站设备（STA）发起测距操作，而不管STA是否处于省电模式，并且不管特定AP是否是目前与STA相关联。例如，为了从非关联AP发起与STA的测距操作，非关联AP获取相关AP的TSF定时器，然后使用获得的TSF定时器来导出相关联的AP的信标传输调度，从而确定何时 STA的相应的唤醒周期发生。此后，非关联AP可以在STA唤醒周期期间与STA发起测距操作，从而确保从非关联AP发送的探测将到达STA，同时STA从节电模式唤醒。

摘要： A hybrid STP can be implemented in a hybrid communication network to prevent communication loops without disabling network interfaces of hybrid devices and redundant paths of the hybrid communication network, while preserving the advantages of the hybrid communication network. Each network interface of a hybrid device can be designated as a relay interface or a non-relay interface. Each of the relay interfaces is independent of the other network interfaces of the hybrid device. The non-relay interfaces operate as a single virtual interface and do not forward packets between each other. Each network interface of the hybrid device may also be associated with a forwarding bit that indicates whether broadcast packets should be forwarded via the network interface. The hybrid device can determine whether/how to forward a packet depending on whether an ingress interface is a relay or non-relay interface and a forwarding bit value of the ingress interface.
摘要翻译：可以在混合通信网络中实现混合STP，以防止通信环路，而不会阻止混合设备的网络接口和混合通信网络的冗余路径，同时保持混合通信网络的优点。混合设备的每个网络接口可以指定为中继接口或非中继接口。每个中继接口独立于混合设备的其他网络接口。非中继接口作为单个虚拟接口运行，不会相互转发数据包。混合设备的每个网络接口也可以与指示广播分组是否应经由网络接口转发的转发比特相关联。混合设备可以根据入口接口是中继还是非中继接口以及入口接口的转发比特值来确定/如何转发数据包。

摘要： A hybrid SAR ADC can be implemented to reduce the number of operations that are executed to convert an analog input signal into its digital representation. Pipeline processing operations can be executed on the analog input signal to generate pipeline bits (MSBs of the digital representation) and an analog residue signal. The analog residue signal can be compared against a plurality of thresholds to generate comparator bits that are indicative of a range associated with a subset of the predetermined thresholds that correspond to the analog residue signal. Successive approximation analog-to-digital conversion operations can be executed on the analog residue signal to generate successive approximation bits. The digital representation can be determined based, at least in part, on the pipeline bits, the comparator bits, and the successive approximation bits.

摘要： This disclosure is directed to a wireless device with a suppressor that couples to the aggressor signal of a frequency source to generate a cancelling signal for suppressing spurs resulting from operation of the frequency source. The amplitude and phase delay of the cancelling signal are adjusted to optimize the cancellation of the spur. Preferably, a calibration routine is performed to establish appropriate delay and amplitude values to cancel the spurs occurring at each device gain setting.

摘要： A programmable voltage to current converter is described that is highly linear and may be implemented with a compact MOSFET switching network. With this design, the power consumption is also minimized. The programmable voltage to current converter comprises a switch network comprising one or two sets of N switches and one or two sets of N resistors, an op amp, and a current buffer MOSFET. The output current is independent of the characteristics of the one or two sets of N switches. To implement a single-ended converter, the switch network comprises one set of N resistors and one set of N switches. To implement a differential-ended converter, the switch network comprises two sets of N resistors and two sets of N switches.
