A receiving device, user equipment, communication system and a method for processing synchronization information are provided. The receiving device comprises a synchronization information processing apparatus configured to combine synchronization information of a plurality of frequency channels based on time and frequency.

In a packet-based communication system, a transmitter and a receiver implement low power synchronization techniques. The transmitter transmits a packet that includes a two-part preamble. A first part of the two-part preamble is transmitted at a first reduced bandwidth that is smaller than a second bandwidth of the channel, and at least one of a second part of the two-part preamble and another portion of the packet is transmitted at the second bandwidth of the channel. The receiver includes an interleaved analog-to-digital converter (ADC) including multiple sub-ADCs. The receiver turns on a first subset of the multiple sub-ADCs during an idle listening period, and turns on a second subset of the multiple sub-ADCs upon detection of a completion of the first part of the two-part preamble, wherein the first subset of the multiple sub-ADCs is less than the second subset of the multiple sub-ADCs.

Methods and architectures for blind detection of physical layer control (PLC) signaling for transmitters and receivers having respective misaligned inverse fast Fourier transforms (IFFTs) and (FFTs) includes opening a frequency tracking offset calibration circuit, estimating or calculating a phase discontinuity due to FFT misalignment, closing the frequency tracking offset calibration circuit and applying a frequency correction that includes a frequency offset less the calculated or estimated phase discontinuity.

A wireless control device comprising: a communication circuit configured to receive, from a wireless device, a signal wirelessly received by the wireless device; and a control circuit configured to store a time at each reception of a given amount of signal by the communication circuit and perform wireless signal processing of transmitting and receiving a wireless signal through the wireless device, in accordance with a time calculated based on a plurality of stored times.

A policer system on one or more place and/or route blocks. The policer system including a plurality of local physical policers each stored in a plurality of physical memory banks and coupled with a plurality of global policers stored in one or more global banks separate from the physical banks. Thus, each bank of the global policers are able to represent a logical combination of a plurality of the physical banks of physical policers.

A control station serving as a base-station control device that issues an operation instruction to each of base stations in a wireless communication system in which a plurality of base stations perform transmission at the same time and the same frequency, wherein a frequency offset of a reception signal from a mobile station that is detected by each of the base stations is collected, and a phase rotation amount that is a rotation amount when the base stations rotate a phase of a transmission signal is determined for each of the base stations so that frequency offsets of the respective transmission signals having been subjected to phase rotation by the respective base stations are the same.

A User Equipment, UE, supporting communication in a multicarrier radio communication system and a method therein for receiving information from a Radio Base Station, RBS, are provided. The method comprises determining 310 a bandwidth by which the UE will receive information, the bandwidth comprising a plurality of sub-carriers. The method also comprises adjusting 320 a bandwidth of the UE to correspond to the determined bandwidth by which the UE will receive information; and fine tuning 330 a local oscillator of the UE such that a centre frequency of a local oscillator does not coincide with a predetermined subcarrier transmitted from the RBS.
