Patent number: 8462689Abstract: A technique for a time division multiplex system in which access to shared broadcast communication media is granted on a demand basis. Particular connections are assigned slot times at the transmitter based on demand. However, no specific information regarding the assignment of time slots need be communicated to the receivers. The transmit side employs a forward error correction technique followed by multiplication by a cover sequence unique to each connection. All receivers listen to the broadcast transmission channel all of the time. The receiver assigned to each connection decodes the signals in such a manner that only the receiver with the correct cover sequence assigned to a particular connection will successfully decode the data associated with that connection. Data frames that fail the forward error correction process are discarded, and only those frames which are successfully decoded are passed up to a higher layer.Type: GrantFiled: December 22, 2004Date of Patent: June 11, 2013Assignee: Intel CorporationInventors: Kevin P. Johnson, Antoine J. Rouphael, George Rodney Nelson, Jr.

Patent number: 8432876Abstract: A control channel supporting traffic control in epochs is divided into two control subchannels each being less than or equal to about a half epoch in duration and occurring serially in time. Slot allocation data may be transmitted and received independently over the subchannels. One subchannel may be used for transmitting forward slot allocation data and the other subchannel may be used for transmitting reverse slot allocation data. The channel split into two subchannels may be a paging channel. The forward and reverse slot allocation data may be transmitted between a base station processor and field unit. Forward and reverse traffic data may be staggered by at least about half an epoch. Transmission of traffic data happens within about two epochs after the assignments.Type: GrantFiled: March 12, 2009Date of Patent: April 30, 2013Assignee: IPR Licensing, Inc.Inventors: John B.

Patent number: 8320298Abstract: Parallel demodulators are provided in field units. Forward and reverse channel allocation information may be broadcast to the field units in the same epoch as traffic data but on first and second channels, such as paging and traffic channels. This assures that all field units are able to receive forward and reverse channel allocation information every epoch. By having parallel demodulators in the field unit, switching between the first and second channels is avoided and channel allocation information is not lost.Type: GrantFiled: January 22, 2003Date of Patent: November 27, 2012Assignee: IPR Licensing, Inc.Inventors: John B.

Patent number: 8296455Abstract: A personal computer's (PC) microprocessor is used to provide both the physical layer (PHY) and media access control (MAC) processing functions required to implement a wireless local area network (WLAN) adapter. This technique uses the polling mechanism associated with the power save (PS) functionality of WLAN protocol to relieve networking stress on the host processing system. It does this while maintaining networking integrity and packet delivery. The WLAN protocol polling mechanism is used to briefly inhibit the transfer of packets from the WLAN access point (AP) during peak periods of network traffic and/or host processor loading. Because the modulation, demodulation, and MAC functions, typically implemented in dedicated hardware on existing adapters are implemented in software running on the host PC microprocessor, other host system processes and applications can interfere with these time critical functions.Type: GrantFiled: August 15, 2007Date of Patent: October 23, 2012Assignee: Intellectual Ventures I LLCInventors: Richard Douglas Schultz, George Rodney Nelson, Jr., John Erich Hoffmann

Publication number: 20120250798Abstract: The present invention provides for making code rate adjustments and modulation type adjustments in a pseudonoise (PN) encoded CDMA system. Coding rate adjustments may be made by changing the number of information bits per symbol, or Forward Error Code (FEC) coding rate. A forward error correction (FEC) block size is maintained at a constant amount. Therefore, as the number of information bits per symbol are increased, an integer multiple of bits per epoch is always maintained. The scheme permits for a greater flexibility and selection of effective data rates providing information bit rates ranging from, for example, approximately 50 kilobits per second to over 5 mega bits per second (Mbps) in one preferred embodiment.Type: ApplicationFiled: June 11, 2012Publication date: October 4, 2012Applicant: IPR LICENSING, INC.Inventors: John E. Hoffmann, George Rodney Nelson, JR., Daniel I. Riley, Antoine J. Rouphael, James A. Proctor, JR.

Patent number: 8175120Abstract: Multiple field units in a CDMA system are synchronized for communication with a base station using a shared forward and reverse link channel. Each field unit is assigned a time slot in a forward link channel to receive messages from the base station. Likewise, each field unit is assigned a time slot on a common reverse link channel for transmitting messages to the base station. Timing alignment among each of many field units and the base station is achieved by analyzing messages received at the base station in a corresponding time slot from each field unit. Thereafter, a message is transmitted in a corresponding time slot to a particular field unit from the base station for adjusting its timing so that future messages transmitted from the field unit are received in the appropriate time slot at the base station.Type: GrantFiled: February 7, 2001Date of Patent: May 8, 2012Assignee: IPR Licensing, Inc.Inventors: G.

Publication number: 20120087364Abstract: A technique for encoding digital communication signals. Data symbols are augmented in pilot symbols inserted at predetermined positions. The pilot augmented sequence is then fed to a deterministic error correction block encoder, such as a turbo product coder, to output a coded sequence. The symbols in the error correction encoded sequence are then rearranged to ensure that the output symbols derived from input pilot symbols are located at regular, predetermined positions. As a result, channel encoding schemes can more easily be used which benefits from power of two length block sizes.Type: ApplicationFiled: December 5, 2011Publication date: April 12, 2012Applicant: IPR LICENSING, INC.Inventors: John E.

Patent number: RE43322Abstract: A personal computer's (PC) microprocessor is used to provide both the physical layer (PHY) and media access control (MAC) processing functions required to implement a wireless local area network (WLAN) adapter. This technique uses the microprocessor within the personal computer to pre-compute the time critical PHY waveforms required to respond to received packets. For instance, the acknowledge (ACK) waveform required to respond to a received WLAN packet is pre-computed and stored in the PC memory. Upon receipt of a valid packet, the samples of the ACK waveform are transferred from the PC memory to a digital to analog converter (DAC). The DAC generates the transmit waveform required for the radio modulator. By pre-computing the transmit waveform samples, the required loading on the PC microprocessor is reduced during time critical periods.Type: GrantFiled: September 11, 2009Date of Patent: April 24, 2012Assignee: Intellectual Ventures I LLCInventors: Richard Douglas Schultz, George Rodney Nelson
