Abstract: A secure ranging system can use a secure processing system to deliver one or more ranging keys to a ranging radio on a device, and the ranging radio can derive locally at the system ranging codes based on the ranging keys. A deterministic random number generator can derive the ranging codes using the ranging key and one or more session parameters, and each device (e.g. a cellular telephone and another device) can independently derive the ranging codes and derive them contemporaneously with their use in ranging operations.

Abstract: Some embodiments include a system, method, and computer program product for managing the Ultra Wideband (UWB) systems, especially when the UWB system is collocated with another wireless system (e.g., WiFi) to transmit and/or receive UWB signals with an occupied bandwidth (OBW) that satisfies a UWB OBW standard (e.g., a UWB OBW>=500 MHz.) In some embodiments a TailBit signal (e.g., a periodic signal at a selected frequency) is added to a UWB packet to generate frequency components at the selected frequency that enables the power spectrum of the TailBit UWB signal to satisfy the UWB OBW standard. In some embodiments an altered code sequence is used to generate an altered spread signal, where the altered code sequence reduces or removes a frequency component peak near DC frequency of the power spectrum of an altered UWB signal, resulting in altered UWB OBW that satisfies the UWB OBW standard.

Abstract: A device implementing signal validation for secure ranging includes at least one processor configured to obtain a channel estimate based at least in part on a signal received from an other device over a channel. The at least one processor may be further configured to determine an average noise level of a beginning portion of the channel estimate and establish a direct path signal acceptance level for the channel estimate based at least in part on the average noise level. The at least one processor may further configured to identify a candidate direct path signal for the channel in a remaining portion of the channel estimate and validate the candidate direct path signal as a direct path signal for the channel when a signal level corresponding to the candidate direct path signal satisfies the direct path signal acceptance level, otherwise reject the candidate direct path signal as the direct path signal for the channel.

Abstract: A user equipment (UE) including at least two antennas configured to allow the UE to communicate via a first connection. The UE selects a connection performance parameter associated with the first connection, generates historical measurement information for the at least two antennas based on the connection performance parameter, for the plurality of antennas, the historical measurement information indicating an expected performance associated with using a selected one of the at least two antennas for a packet transmission and selects, based at least on the historical measurement information, one of the at least two antennas for use in transmitting the packet.
