摘要： In a wireless 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.

摘要： In cellular radio systems it is a problem to provide service to UE (user equipment) on the cell border. In systems that apply a frequency re-use of one, and OFDM access technology, the uplink direction need be improved. One embodiment of this application relates to a radio base station that is equipped with one or more FFT processor/s in addition to the FFT-processor that is adapted for being adjusted to the timed aligned arrival of signals from UE served by the radio base station. The additional FFT processor/s is adapted for being adjusted to the arrival of one or more signals from UE that are served by other radio base station/s. The radio base station is further adapted to send Fourier processed signal information relating to the UE of the other radio base station/s and thereby assist the other radio base station in signal reception. The application also relates to a method for assisting another radio base station in signal reception, and to a method for receiving assistance from another radio base station in signal reception.

摘要： An xDSL communication system (100) using Discrete Multi-tone (DMT) symbols sent over a channel. The magnitude of the channel's frequency-domain equalizing filter (112d) is normalized, leaving only phase information. The inverse discrete Fourier Transform (150) of the normalized filter gives a peak at a position which corresponds to the group time delay of the transmitted DMT symbol. Identification of the symbol boundary facilitates synchronization of the receiver symbol phase to the transmitter symbol phase.

摘要： An exemplary method is implemented by a radio frequency receiver for synchronizing the recovery of data carried by frames received by a radio frequency communication. An initial carrier frequency estimate is used to initialize the carrier recovery system to synchronize the data unit contained in a first frame. An indication is generated, from error correction applied to the identified data units for each frame, of whether the error control coding in the receiver is capable of correcting all the errors induced by the channel within the frame. If the indication declares that all the errors are corrected, then the carrier frequency estimate associated with the error free frame is saved in memory and will be used to initialize the carrier recovery loop at the beginning of the following frames until such frequency estimate is declared unreliable. A new carrier frequency estimate is available at the end of each frame, and if such estimate is proven to be reliable for future use, the current estimate in memory will be overwritten by the new estimate and the freshness of the frequency estimate is extended.
摘要翻译：一种示例性方法由射频接收机实现，用于同步由通过射频通信接收的帧承载的数据的恢复。使用初始载波频率估计来初始化载波恢复系统以使包含在第一帧中的数据单元同步。从针对每帧的识别的数据单元的误差校正产生接收机中的错误控制编码是否能够校正由帧内的信道引起的所有错误的指示。如果指示声明所有错误都被纠正，则与无错帧相关联的载波频率估计被保存在存储器中，并且将被用于在随后帧的开始处初始化载波恢复循环，直到这种频率估计被宣告为不可靠。新的载波频率估计在每帧结束时可用，如果这种估计被证明是可靠的将来使用，则存储器中的当前估计将被新估计覆盖，并且频率估计的新鲜度得到延长。
