An apparatus and method for non-exclusive multiplexing of at least one active control channel comprising preparing the at least one active control channel for transmission in a next frame using a transmitter data processor; assessing channel robustness of the at least one active control channel based on a channel robustness threshold; and if the channel robustness threshold is not met, performing constellation control or power control on the at least one active control channel which is active prior to transmitting the at least one active control channel; or if the channel robustness threshold is met, transmitting the at least one active control channel using a transmitter.

Apparatus and method for channel error control of non-exclusive multiplexing for control channels

A method for determining electrical condition of a wired drill pipe includes inducing an electromagnetic field in at least one joint of wired drill pipe. Voltages induced by electrical current flowing in at least one electrical conductor in the at least one wired drill pipe joint are detected. The electrical current is induced by the induced electromagnetic field. The electrical condition is determined from the detected voltages.

Method and apparatus for locating faults in wired drill pipe

A method is provided for compensating for clock drift error and movement error of an access terminal. A forward link error is obtained that is attributable to at least a first error (e.g., clock drift error) component and a second error (e.g., movement error) component. The first error component and the second error component are estimated based on the obtained forward link error. A receive clock of the access terminal is compensated based on a combination of the first error component and the second error component. A transmit clock of the access terminal is compensated based on a difference between the first error component and the second error component. The forward link error may include a timing synchronization error between the access terminal and an access point as well as a frequency synchronization error between a forward link frequency and a baseband reference frequency.
