Patent number: 9124477Abstract: A communication device includes a communication interface and a processor. In one example, the processor generates an orthogonal frequency division multiplexing (OFDM) symbol that includes information modulated within sub-carriers and then interleaves the sub-carriers of the OFDM symbol to generate an interleaved OFDM symbol. This interleaving of the sub-carriers operates to write the plurality of sub-carriers to rows of a two dimensional (2D) array and read the plurality of sub-carriers from columns of the 2D array. This interleaving also operates to read a column of the columns using a bit-reversed address of the column when the bit-reversed address is less than a number of the columns and using the address of the column when the bit-reversed address is greater than or equal to the number of the columns. The processor transmits, via the communication interface, the interleaved OFDM symbol to another communication device.Type: GrantFiled: August 28, 2014Date of Patent: September 1, 2015Assignee: Broadcom CorporationInventors: Avraham Kliger, Tak Kwan Lee, Richard Stephen Prodan, Ba-Zhong Shen, Yitshak Ohana

Publication number: 20150128004Abstract: A communication device (or device) includes a communication interface and processor that support communications with one or more other devices within a communication system. The processor generates and interprets different signals, frames, packets, symbols, etc. for transmission to other devices and that have been received from other devices. The device generates modulation symbols based on two-dimensional (2-D) symbol locations of a constellation. The device generates the 2-D symbol locations using based on recursive one-dimensional (1-D) Gray code formula applied to bits of symbol values. The recursive 1-D Gray code formula specifies first symbol locations for symbol values having a first number of bits (e.g., n) based on second symbol locations for other symbol values having one fewer bits per symbol (e.g., n?1). The device maps data symbols to the 2-D symbol locations to generate the modulation symbols and transmits the modulation symbols to another communication device.Type: ApplicationFiled: October 28, 2014Publication date: May 7, 2015Applicant: BROADCOM CORPORATIONInventors: Tak Kwan Lee, Ba-Zhong Shen

Publication number: 20150095726Abstract: A communication device operates to support communications with one or more other communication devices. The communication device includes a processor and a communication interface to perform various operations including receiving forward error correction (FEC) coded signals from another communication device. The communication device iteratively decodes the FEC coded signals to make estimates of information encoded therein. The communication device then determines an operational error check rate based on error check failure of at least one of the FEC coded signals after performing a predetermined number of decoding iterations (e.g., that is less than a maximum number of decoding iterations performed by the device). The device then determines a signal to noise ratio (SNR) margin of the communication device by applying the operational error check rate to a characterization of the communication device that relates error check rate and SNR.Type: ApplicationFiled: September 29, 2014Publication date: April 2, 2015Applicant: BROADCOM CORPORATIONInventors: Kelly Brian Cameron, Hau Thien Tran, Tak Kwan Lee, Ba-Zhong Shen, Bruce Joseph Currivan

Patent number: 8115499Abstract: The electrical equivalent of a relatively large area proximity detection capability is provided in a space limited electronic device (20, 30) with many individual input electrodes (24, 34, 44) by dynamically coupling parallel groups of the individual electrodes (24, 34, 44) and applying a proximity and/or contact test thereto. The parallel grouped electrodes act like a single large electrode and permit proximity detection at greater distances and with greater sensitivity. A multiplexer (74) automatically couples individual input electrodes (23, 24, 44) and then parallel grouped electrodes to the proximity (or contact) sensor(s) (46, 66), so that they are scanned and sensed individually and collectively in a time less than human reaction time, whereby the proximity sense function appears as if provided by a separate large area electrode. Proximity spatial detection accuracy is increased by using some of the electrodes (24, 34, 44) as driven shields to remove positional ambiguity.Type: GrantFiled: May 22, 2009Date of Patent: February 14, 2012Assignee: Freescale Semiconductor, Inc.Inventors: Bryce T.

Publication number: 20070018672Abstract: A method and apparatus is presented for gaining socket testability through the use of a capacitive interposer engineered to create capacitive coupling between signal nodes of a circuit assembly that the tester has access to and nodes of the socket that would not otherwise have any coupling to a testable signal node of the socket. Generally, coupling capacitance is engineered into the interposer by trace and via routing between the signal node of the socket and a location in close proximity to the inaccessible socket node such that their proximity to each other couples them together.Type: ApplicationFiled: July 23, 2005Publication date: January 25, 2007Inventors: Chris Jacobsen, Kenneth Parker, Myron Schneider, Tak Kwan
