Publication number: 20140092882Abstract: Methods and apparatus are described for mitigating intercell interference in wireless communication systems utilizing substantially the same operating frequency band across multiple neighboring coverage areas. The operating frequency band may be shared across multiple neighboring or otherwise adjacent cells, such as in a frequency reuse one configuration. The wireless communication system can synchronize one or more resource allocation regions or zones across the multiple base stations, and can coordinate a permutation type within each resource allocation zone. The base stations can coordinate a pilot configuration in each of a plurality of coordinated resource allocation regions. Subscriber stations can be assigned resources in a coordinated resource allocation region based on interference levels. A subscriber station can determine a channel estimate for each of multiple base stations in the coordinated resource allocation region to mitigate interference.Type: ApplicationFiled: December 6, 2013Publication date: April 3, 2014Applicant: Wi-LAN Inc.Inventors: Hari Sankar, Ron Porat, Danjie Pan, Wee Peng Goh, Srikanth Gummadi, Lei Wang

Publication number: 20140072021Abstract: In an orthogonal frequency division multiplex (OFDM) communication network, a node transmits an echo profile probe to other nodes in the network. The echo profile probe is a message that allows characterization of the unique echo profile through the communication channel between each node pair. The echo profile is used to calculate the cyclic prefix length needed for optimum communication from one node to the other.Type: ApplicationFiled: November 15, 2013Publication date: March 13, 2014Applicant: Entropic Communications, Inc.Inventors: Wee Peng GOH, Anton MONK, Ron PORAT

Patent number: 8621539Abstract: A physical layer transmitter that communicates between nodes in a broadband cable network by transmitting and receiving packets containing data and control information. Packets are constructed by the physical layer transmitter and transmitted to one or more receiving nodes that are capable of processing the packets. Packets are directed to specific nodes utilizing link layer control data. The packets may also contain control information that may include formatting, encoding and modulation parameters that are capable of being processed by the appropriate receiving nodes. The physical layer transmitter allows node-to-node communication within a broadband cable network and each node in the network is capable of communicating with every other node in the network.Type: GrantFiled: September 29, 2005Date of Patent: December 31, 2013Assignee: Entropic Communications, Inc.Inventors: Anton Monk, Ron Porat, Wee Peng Goh, Magnus Berggren, Ron Lee, Edward Warner, Brett Bernath, Yusuf Ozturk

Patent number: 8432999Abstract: An efficient algorithm is described for use with OFDM receivers that characterizes the impulse response of a communication channel using frequency domain techniques that reduce computational and memory requirements, relative to time-domain cross-correlation methods, without sacrificing algorithm performance. An FFT engine is used to transform a time domain input sequence, the transformed sequence is multiplied by the conjugate of the expected sequence, the product of several sequences is averaged, then the FFT engine transforms the average back to a time domain sequence, the magnitude of which is the impulse response of the channel.Type: GrantFiled: October 17, 2011Date of Patent: April 30, 2013Assignee: Entropic Communications, Inc.Inventors: Wee Peng Goh, Jason Beck, Raja Gosula

Patent number: 7738355Abstract: In a communication network, a sending node transmits a message with a multisegment preamble and data to a receiving node. The receiving node calculates characteristics of the sending unit, channel, or transmitted signal by processing preamble segments. Once an unknown characteristic is determined, a segment of the preamble can be eliminated or reduced in length for subsequent messages, which increases efficiency of the message transmissions.Type: GrantFiled: September 16, 2005Date of Patent: June 15, 2010Assignee: Entropic Communications, Inc.Inventors: Wee Peng Goh, Anton Monk, Ron Porat
