  • METHOD AND APPARATUS FOR VARIABLE HEADER REPETITION IN A WIRELESS OFDM NETWORK WITH MULTIPLE OVERLAPPED FREQUENCY BANDS
    Publication number: 20170063415
    Abstract: Method and apparatus for use within a wireless OFDM network that transmits and receives first and second packets each having header bits and utilizing variable header repetition. The header bits in the first packet are communicated on multiple OFDM symbols and repeated on a plurality of OFDM subcarriers in a first frequency band. The header bits in a second packet are communicated on fewer OFDM symbols and in a second frequency band that overlaps with and is wider than the first frequency band.

  • METHOD OF DETECTING PACKET BANDWIDTH IN A WIRELESS OFDM NETWORK WITH MULTIPLE OVERLAPPED FREQUENCY BANDS
    Publication number: 20160255178
    Abstract: A wireless OFDM transceiver uses a method of detecting subcarrier characteristics, such as phase and amplitude, to determine the bandwidth of a received packet. By detecting different subcarrier characteristics in the long training symbols of a packet at the receiver, the packet is associated with different bandwidths. The different bandwidths are used in a wireless network where devices can communicate using two frequency bands that overlap one another and where one is wider than the other.

  • Method of controlling performance of auto color registration and image forming apparatus using the same
    Patent number: 9354574
    Abstract: A method of controlling performance of auto color registration (ACR) of a color image forming apparatus, and an image forming apparatus using the same are provided. The method of controlling performance of ACR includes forming a composite black image on a transfer belt, sensing the composite black image by using a sensor, measuring the sensed composite black image, and performing ACR correction when a measured width of the composite black image is greater than a previously set value. Accordingly, it is possible to prevent unnecessary performance of ACR control when no color misregistration has occurred. In this way, ACR control is performed in as short a time as possible so that performance of the image forming apparatus may be improved. Also, it is possible to prevent waste of ACR performance time and life span reduction of a driving source for ACR.

  • PACKET DETECTOR
    Publication number: 20160020934
    Abstract: There are several exemplary ways to more efficiently communicate an out-of-domain seed to a receiver—in a first technique, the seed can be indicated in the header portion or data portion of a packet. For example, the header portion of the packet could contain one or more bit fields that indicate the value of the LFSR seed used for the preamble portion of the packet. The receiver would learn the out-of-domain seed after receiving a first out-of-domain packet and decoding the header portion of that packet. After learning the out-of-domain seed, the receiver could send a packet indicating the value of the out-of-domain seed to the local master. The local master could then transmit the value of the out-of-domain seed in the header portion or data portion of a local MAP frame.
