A method is described and in one embodiment includes detecting a transition of a data signal comprising a data packet received at a circuit while the circuit is in a first hysteresis mode; placing the circuit in a second hysteresis mode subsequent to the detecting; and returning the receiver to the first hysteresis mode subsequent to completion of receipt of the data packet to await receipt of a next data packet. In certain embodiments, the first hysteresis mode is a high hysteresis mode and the second hysteresis mode is a standard hysteresis mode. In some embodiments, a level of each of the first and second hysteresis modes is dynamically tunable.

A wireless microphone system efficiently combines a pair of antennas so that radio frequency (RF) signals may be transmitted to and from multiple receivers and multiple wireless microphones. The wireless microphone system supports a general radio access technology and may comply with a Digital Enhanced Cordless Telecommunications (DECT) specification. The resource manager combines a received RF component with a first digital component via a first coaxial link to a connected receiver. The receiver also combines a transmitted RF component with a second digital component via a second coaxial link to the resource manager. The first digital component further includes synchronization and data sub-components, which are separated at the receiver.

A method for avoiding collision over a communication network, wherein devices are connected to the same medium. Each device has an access control module, a transceiver and a data exchange module. The access control module is configured to transmit data to the data exchange module when it receives information that no data is present on the medium. The transceiver is configured to transmit data on the medium each time it receives data from the data exchange module. The data exchange modules of all the devices are synchronized and then offered, in sequence, the opportunity to transmit data on the medium. The opportunity to transmit is offered dynamically after a previous transmission end or, if no transmission occurred, after a predetermined time range has expired. The data exchange module transmits data to the transceiver of the same device only when it is offered the opportunity to transmit.

In accordance with an embodiment, a method of producing a TDM serial audio stream includes: receiving a plurality of input audio signal streams from an audio source clocked at an input clock frequency and producing therefrom a TDM serial output stream clocked at a TDM output clock frequency; obtaining the input clock frequency and the TDM output clock frequency by dividing a master clock frequency; writing audio signal samples from the input audio signal streams into a set of memory buffers at the input clock frequency; and producing the TDM serial output stream from audio signal samples buffered in the memory buffers by reading the buffered audio signal samples at the TDM output clock frequency.

Disclosed herein are various embodiments that include a method and a passive optical network (PON) for supporting a mobile network. In various embodiments, a baseband unit (BBU) is configured to measure an optical path delay from each remote radio unit (RRU) of a plurality of RRUs to the BBU during an initialization phase. The BBU synchronizes all the RRUs in the mobile system by adjusting the timing of each path based on the optical path delay between each RRU and the BBU. The BBU determines a mapping rule that maps each resource block assigned to each RRU of the plurality of RRUs to a different PON transport block. The BBU transmits the mapping rule to each RRU of the plurality of RRUs. In certain embodiments, the mapping rule may be recalculated dynamically after the initialization phase.

A sensor may determine a sampling pattern based on a group of synchronization signals received by the sensor. The sampling pattern may identify an expected time for receiving an upcoming synchronization signal. The sensor may trigger, based on the sampling pattern, a performance of a sensor operation associated with the upcoming synchronization signal. The performance of the sensor operation may be triggered before the upcoming synchronization signal is received.

A device includes an interface and Time Division Multiple Access (TDMA) Medium Access Control (MAC) circuitry coupled to the interface. The TDMA MAC circuitry detects a beacon in a frame having a defined frame duration and determines a frame compensation value based on a start time of the frame, a reference start time of the frame, and a number of elapsed frames. A current frame duration value is determined based on the frame compensation value and the defined frame duration.

Systems and methods for aligning timing of an inroute transmission of a terminal with a gateway are disclosed. A system may include a processor and a memory storing instructions, which when executed by the processor, may cause the processor to perform a random estimation of location pertaining to a time-division multiple access (TDMA) frame boundary of a gateway. Based on an asynchronous scrambled coded multiple access (ASCMA) technique, the system may transmit ASCMA group burst packets including precise timing feedback request for the gateway. The system may receive a feedback from the gateway, in response to the precise timing feedback request. The processor may determine an adjustment for aligning timing of an inroute transmission of the terminal with respect to the TDMA frame boundary of the gateway. The system may apply the adjustment to synchronize the timing of the inroute transmission of the terminal with the gateway.

Each of the reserved time slots is identified by at least a network ID of a transmitting node in the vehicle network, and a slot type comprising one of a low latency traffic slot, and a bulk traffic slot. Further, the low latency traffic slots are repeated in the TDMA cycle at least as frequently as a guaranteed QoS latency parameter. Further, the bulk traffic slots are at least as long as a guaranteed QoS throughput parameter.
