The receiver captures samples of a received baseband signal at the rate 1/ts′, operates on the captured samples to generate an estimate for the clock rate offset, and fractionally resamples the captured samples using the clock rate offset.

Using sequences for symbol timing synchronization in single-carrier modulation mimo communication systems
A method for symbol timing synchronization in multiple-input multiple-output (mimo) communication, the method including transmitting a first symbol sequence including a preamble symbol sequence s1 from a first transmitting location, transmitting a second symbol sequence from a second transmitting location, the first and second symbol sequences being modulated onto a same carrier frequency, receiving a first mixture of the first and the second symbol sequences at a first receiving location, cross correlating the first mixture with a symbol sequence p1 thereby producing a first correlation output, and determining a first timing offset for receiving the first symbol sequence based, at least in part, on the first correlation output. Related apparatus and methods are also described..

Radar for rejecting and looking past surface reflections
A multi-modal ground penetrating radar includes a radar set configured to launch predistorted double-sideband (dsb) suppressed-carrier modulated continuous waves (cw) to illuminate and penetrate a ground surface. A variable frequency modulator is connected to modulate a continuous wave (cw) carrier frequency generator within the radar set to yield a double-sideband suppressed carrier output.

Method of handling frequency de-prioritization
A method of handling frequency de-prioritization for a communication device in a wireless communication system is disclosed. The method comprises receiving a first radio resource control (rrc) connection reject message with a first deprioritisation request indicating at least one first carrier frequency to be the lowest priority frequency, from a first public land mobile network (plmn) of the wireless communication system, and determining the at least one first carrier frequency to be the lowest priority frequency only when the communication device selects or registers to the first plmn..

Wireless transmitter, wireless receiver, wireless communication system, elevator control system, and transformer equipment control system
Improving the reliability of digital radio communication affected by multi-path interference under an environment where there are multiple objects that scatter electromagnetic waves is accomplished. A wireless transmitter transmits a first transmission wave having a first carrier frequency (f0+Δf), modulated by a modulator with an information signal having a frequency band f1 which is predetermined, from a transmitting antenna, and transmits a second transmission wave having a second carrier frequency (f0−Δf), modulated by a modulator with such information signal.
