Patent number: 9350438Abstract: A relay receives a frame from a source, and based on state of a relayed frame bit within the frame, the relay selects an operational mode: implicit acknowledgement mode, first explicit acknowledgement mode, or second explicit acknowledgement mode. The relay sets the relayed frame bit in subsequent transmissions to indicate transmission opportunity (TXOP) control of the communication medium (e.g., whether under control of the relay or the source). The source may receive acknowledgement of the relay's successful receipt of the frame implicitly via the relay transmitting a relayed frame to the destination. Alternatively, the source may receive acknowledgement of the relay's successful receipt of the frame explicitly in a response frame from the relay. State of a more data bit in the frame receive from the source may indicate the source has one or more additional frames intended for the destination.Type: GrantFiled: July 31, 2015Date of Patent: May 24, 2016Assignee: Broadcom CorporationInventors: Chiu Ngok Eric Wong, Matthew James Fischer

Patent number: 9350419Abstract: A system for coordinating transmissions of power line communication (PLC) devices may include a processor and a memory. The processor may be configured to receive channel state information (CSI) from primary PLC devices. The primary PLC devices may be communicatively coupled to secondary PLC devices via collocated power lines, such as bundled power lines. Thus, the transmission of a primary PLC device over a power line to a secondary PLC device may be electromagnetically coupled onto the other power lines, thereby causing far-end crosstalk (FEXT) interference with respect to other secondary PLC devices. The processor may be configured to determine precoding information for compensating for the FEXT interference based at least on the received CSI. The processor may be configured to provide at least a portion of the precoding information to the primary PLC devices and to coordinate precoded transmissions of the primary PLC devices to mitigate the FEXT interference.Type: GrantFiled: November 21, 2013Date of Patent: May 24, 2016Assignee: Broadcom CorporationInventors: Xavier Josep Reves Balleste, Yue Sun, Miguel Philippe Paul Peeters, Zacarias Iracheta Todo, Toby Edward Ralph Bailey

Patent number: 9344098Abstract: The present disclosure is directed to a system and method for generating an output oscillating signal using an input oscillating signal that is subject to missing pulses and/or distortions. The output oscillating signal can be generated at a desired frequency by a frequency-locked loop (FLL) that uses the input oscillating signal as a reference clock. Because the input oscillating signal is used as a reference clock, missing pulses and/or distortions in the input oscillating signal can adversely affect the continued, stable generation of the output oscillating signal. To this end, the system and method of the present disclosure use an input oscillating signal error detector to open the FLL upon detecting a missing pulse in the input oscillating signal and/or a distortion in the input oscillating signal.Type: GrantFiled: May 22, 2015Date of Patent: May 17, 2016Assignee: Broadcom CorporationInventors: Georgios Sfikas, Jianfeng Shi

Patent number: 9344278Abstract: Encrypted information is conventionally broken into blocks which are transmitted sequentially. Because the order and the size of such blocks can be easily determined, an eavesdropper can gain valuable information regarding the content of the communication. More specifically, if known types of information exist within a block, the encryption key may be determined allowing the content of other encrypted blocks to be obtained. Embodiments of a system, method and computer program product described herein can overcome this deficiency by securely transferring information through random ordering and random block sizing. An original data set to be transferred is divided into a plurality of blocks, where at least two blocks have different sizes. The blocks are encrypted and inserted into a sequence of data transfer slots. The blocks are then selected for transfer in random order by selecting a slot to transfer based on a generated random number.Type: GrantFiled: May 14, 2012Date of Patent: May 17, 2016Assignee: Broadcom CorporationInventor: Jacob Mendel
