Title: Coding methods of communicating identifiers in peer discovery in a peer-to-peer network
Inventor: LI JUNYI
IPC: H04B7/26
Filed: 2008-07-02
Abstract: Systems and methodologies are described that facilitate identifying peers based upon encoded signals during peer discovery in a peer to peer network. For example, direct signaling that partitions a time-frequency resource into a number of segments can be utilized to communicate an identifier within a peer discovery interval; thus, a particular segment selected for transmission can signal a portion of the identifier, while a remainder can be signaled based upon tones communicated within the selected segment. Moreover, a subset of symbols within the resource can be reserved (e.g., unused) to enable identifying and/or correcting timing offset. Further, signaling can be effectuated over a plurality of peer discovery intervals such that partial identifiers communicated during each of the peer discovery intervals can be linked (e.g., based upon overlapping bits and/or bloom filter information).

Title: Phase-locked loop with self-correcting phase-to-digital transfer function
Inventor: ZHANG GANG
IPC: H03L7/093
Filed: 2008-12-24
Abstract: A phase-locked loop includes a phase-to-digital converter portion as well as a novel correction portion. The phase-to-digital converter (PDC) portion outputs a stream of first phase error words. The novel correction portion receives the first phase error words and generates a stream of second phase error words that is supplied to a loop filter. The PDC portion has a phase-to-digital transfer function that exhibits certain imperfections. In a first example, the correction portion determines an average difference between pairs of first phase error words, and uses this average difference to normalize the first phase error words to correct for changes in PDC portion transfer function slope due to changes in delay element propagation delay. In a second example, the correction portion corrects for gain mismatches in PDC portion transfer function. In a third example, the correction portion corrects for offset mismatches in PDC portion transfer function.
