    Abstract: Embodiments of the invention may provide for reducing interference in the front-end of a communications receiver. The cancellation circuitry may be utilized in conjunction with a preliminary rejection filter for improved rejection of out-of-band interference from other radio services or circuitry. The cancellation circuit may be placed in parallel with the preliminary rejection filter and may enhance suppression at the interference frequency by matching the gain and phase of the preliminary rejection filter prior to subtracting the matched signal from the preliminary rejection filter output. The cancellation circuit need not necessary know beforehand the characteristics of the preliminary rejection filter, the interference source, or the coupling mechanism, as it may adapt to unknown or varying interferers by adapting the matching gain and phase values based on the output of the preliminary rejection filter at tap points occurring both before and after application of the cancellation signal.

    Abstract: A method for reproducing video contents includes the steps of: selecting a reproduction shot from video contents, based on a current location information and a shot index information; determining a reproduction section from the selected reproduction shot; and reproducing the determined reproduction section. After the determined reproduction section is reproduced, the above processes are repeated to next reproduction shots. The repetitive processes are performed all over the video contents until the user requests a reproduction change.

    Abstract: Provided are a transmitter and a receiver. The transmitter combines N data signals received from an encoded bit stream to generate N symbols; maps the N symbols to subcarriers that are spaced more than a coherent bandwidth apart; and receives and moves the N symbols, which are mapped to the subcarriers that are spaced more than a coherent bandwidth apart, to their own positions. The receiver demodulates N pieces of data using the N symbols received from the transmitter in a manner similar to that used by the transmitter.

    Abstract: An apparatus and method for compensating Quality of Service (QoS) during a handover of a Mobile Station (MS) by a serving Base Station (BS) and a target BS in a wireless broadband access system are provided. The method includes generating a message during a handover from the serving BS to a target BS, the message including at least one of a data transmission/reception time just before the handover, a size of a time window for which a data transmission/reception history is recorded in an accumulated way, and an amount of data transmitted/received during the time window, and transmitting the message to the target BS. The target BS can more accurately find a handover break time and the amount of data transmission/reception in the serving BS at the time the MS has been handed over to the target BS, enabling fast and adequate QoS compensation/correction for each QoS class, and thus facilitating flexible, efficient and accurate QoS provisioning regardless of controlled handover and uncontrolled handover.
