Abstract: The present disclosure provides for the construction and use of a set of Zero-Correlation-Zone (ZCZ) Concatenated Complementary Pair (CCP) sequences with zero-correlation-zone range greater than one or with zero-correlation-zone range equal to one and the sequence set size greater than two. Complementary pair sequences A and B are selected and, for each member of the set of ZCZ CCP sequences, sign sequences pA and pB are combined with the complementary pair sequences to form a member ZCZ CCP sequence of the set. A ZCZ CCP sequence modified by propagation over a communication channel may be identified by cross-correlation with ZCZ CCP sequences of the set. A set of sign sequences may be constructed by recursive expansion from an initial set or found by a computer search. The sequences may be used in a transceiver of a portable electronic device or other communication device.

Abstract: Mobile nodes without connectivity to a wireless network form mobile ad hoc networks with mobile nodes with connectivity to the wireless network. The moving directions for the mobile nodes are determined. If the mobile nodes are traveling in substantially the same direction the ad hoc network is formed. The mobile nodes then exchange capabilities. If a mobile node without connectivity to a particular network determines that another mobile node in the ad hoc network is connected to the network, the mobile node without connectivity can tunnel data to the network through the other mobile node.

Abstract: A mobile device and a method and circuit for determining a position of the mobile device is disclosed. A positioning signal is received at a communication circuit of the mobile device.

A switch may be configured to selectively couple the position-determining module to the communication circuit.

Abstract: The present disclosure provides for a method and apparatus for efficient cross-correlation between a reference sequence and a received sequence in a wireless communication system. The reference sequence includes a concatenation of sign-adjusted sub-sequences, the sign adjustments determined by a first sign sequence of a set of sign sequences. For example, the reference sequence may be an alternating concatenation of sign-adjusted Golay complementary pair sub-sequences. The received sequence is shifted to provide a plurality of time shifted sequences that are then cross-correlated with the sub-sequences to form a set of partial cross-correlations. The partial cross-correlations are sign-adjusted using the first sign sequence and combined to produce the cross-correlation between the reference sequence and the received sequence. The cross-correlations so produced may be used for channel signature (e.g. PHY-type) identification and/or channel impulse response estimation.

Abstract: Disclosed are a queue controller and method thereof for dual mode I/O devices and methods for transmission of a short range radio link such as a Bluetooth link that is a bi-directional real-time audio communication signal that can be over a first transport or a second transport. The described queue controller can transform a single input queue having heterogeneous packet types to a queue having homogeneous packet types in a case where heterogeneous audio packet types are anticipated. According to control signals that can be based upon operating conditions and transport selection, a first control signal or a second control signal can control the single input queue transformation. After a transport is selected, a single input queue can be processed by a queue controller configured to transform the single input queue having heterogeneous packet types to a queue having homogeneous packet types.

Abstract: Disclosed are dual mode I/O devices and methods for transmission of a short range radio link such as a Bluetooth® link that is a bi-directional real-time audio communication signal that can be over a synchronous circuit-switched transport and an asynchronous packet-switched transport either sequentially or simultaneously. Also disclosed are dual mode wireless headset systems and methods of at least two dual mode I/O devices and more particularly including a wireless audio terminal and an audio gateway for transmission of a bi-directional real-time audio communication signal that can be over a synchronous circuit-switched (SCO) transport and an asynchronous packet-switched (ACL) transport either sequentially or simultaneously. Having both SCO and ACL modes available may allow the user to optimize voice quality or data throughput under different operating conditions. The user may benefit from better Bluetooth®voice quality and may have the flexibility of using either mode depending upon the situation.
