Publication number: 20130215745Abstract: Dynamic buffer management for wireless communication systems facilitates enhanced throughput. The dynamic buffer management reduces buffer allocation for the current service period near the end of the current service period, and allocates the freed buffer space to one or more subsequent service periods before they begin. As a result, the host may begin to transfer data for those subsequent service periods in advance, so that data is immediately available to send when the subsequent service periods begin.Type: ApplicationFiled: February 16, 2012Publication date: August 22, 2013Applicant: Broadcom CorporationInventors: Srikanth Shubhakoti, Hyun-Gyu Jeon, Hongyu Xie, Gang Lu

Patent number: 8516331Abstract: In conventional Backplane Ethernet systems, data is transmitted over two pairs of copper traces in one direction using a PAM-2 scheme and a baud rate of 10.3125 GHz, giving an effective bit rate of 10.3125 Gbps. The rate at which data can be transmitted in Backplane Ethernet systems, while still being reliably received, is typically limited by ISI caused by the dispersive nature of the copper traces, frequency dependent transmission losses caused primarily by skin effect and dielectric loss of the copper traces, and cross-talk from adjacent communication lines. The present invention is directed to systems for overcoming these and other signal impairments to achieve speeds up to, and beyond, twice the conventional 10 Gbps limit associated with Backplane Ethernet systems.Type: GrantFiled: January 26, 2011Date of Patent: August 20, 2013Assignee: Broadcom CorporationInventors: William Bliss, Vasudevan Parthasarathy

Patent number: 8515054Abstract: A signal processing system which discriminates between voice signals and data signals modulated by a voiceband carrier. The signal processing system includes a voice exchange, a data exchange and a call discriminator. The voice exchange is capable of exchanging voice signals between a switched circuit network and a packet based network. The signal processing system also includes a data exchange capable of exchanging data signals modulated by a voiceband carrier on the switched circuit network with unmodulated data signal packets on the packet based network. The data exchange is performed by demodulating data signals from the switched circuit network for transmission on the packet based network, and modulating data signal packets from the packet based network for transmission on the switched circuit network. The call discriminator is used to selectively enable the voice exchange and data exchange.Type: GrantFiled: August 10, 2010Date of Patent: August 20, 2013Assignee: Broadcom CorporationInventors: Wilf LeBlanc, Shawn Stevenson, Bill Boora
