Abstract: Timing acquisition may be performed without typical correlation computations by determining a power of a received signal at certain points in time and using the determined power to identify gaps in the received signal. By determining gaps in the received signal, frame timing may be estimated, particularly in time-division networks where the location of guard periods within a frame is known. Gap detection may thus be used for timing acquisition.

Abstract: Methods and apparatus for managing interference are described and may include updating a covariance inverse value of a linear function to remove an effect on the linear function of a first set of channels associated with a first network entity, wherein the first set of channels are cancelled in response to performing a first cancellation procedure. Methods and apparatus for managing interference may further include performing a second cancellation procedure to cancel a second set of channels associated with a second network entity based at least in part on the updated covariance inverse value of the linear function.

Abstract: Implementations generally relate to ultrasonic communication between devices. In some implementations, a method includes receiving a data signal, where the data signal is transmitted and received in an indoor environment. The method further includes demodulating the data signal based on direct sequence spread spectrum.
