Multiplexing and transmission of multiple data streams in a wireless multi-carrier communication system

02/13/14 - 20140044094 - Techniques for multiplexing and transmitting multiple data streams are described. Transmission of the multiple data streams occurs in “super-frames”. Each super-frame has a predetermined time duration and is further divided into multiple (e.g., four) frames. Each data block for each data stream is outer encoded to generate a corresponding code
Inventors: Rajiv Vijayan, Aamod Khandekar, Fuyun Ling, Gordon Kent Walker, Murali Ramaswamy Chari

Peak-to-average power ratio management for multi-carrier modulation in wireless communication systems

09/05/13 - 20130230003 - Techniques for managing peak-to-average power ratio (PAPR) for multi-carrier modulation in wireless communication systems. Different terminals in a multiple-access system may have different required transmit powers. The number of carriers to allocate to each terminal is made dependent on its required transmit power. Terminals with higher required transmit powers may
Inventors: Rajiv Vijayan, Avneesh Agrawal, Sanjay Jha

System and method for frequency diversity

06/20/13 - 20130156124 - A system and method for frequency diversity uses interleaving in a wireless communication system utilizing orthogonal frequency division multiplexing (OFDM) with various FFT sizes. Subcarriers of one or more interlaces are interleaved in a bit reversal fashion and the one or more interlaces are interleaved in the bit reversal fashion.

Scalable frequency band operation in wireless communication systems

01/05/12 - 20120002623 - To support mobile stations that are not capable of demodulating the entire bandwidth or that can be made to demodulate less than the entire bandwidth, a system, apparatus and method are provided to schedule users on less than all of the bandwidth. Further, certain users can be scheduled on more
Inventors: Aamod Khandekar, Alexei Gorokhov, Avneesh Agrawal, Rajiv Vijayan, Edward Harrison Teague, Fatih Ulupinar

Method and apparatus for seamlessly switching reception between multimedia streams in a wireless communication system

12/08/11 - 20110302605 - Techniques to seamlessly switch reception between multimedia programs are described. For “continued decoding”, a wireless device continues to receive, decode, decompress, and (optionally) display a current program until overhead information needed to decode the new program is received. For “early decoding”, the wireless device receives a user input and identifies
Inventors: Murali Ramaswamy, Gordon Kent Walker, Rajiv Vijayan

Wide area and local network id transmission for communication systems

03/10/11 - 20110058469 - The embodiments utilize OFDM symbols to communicate network IDs. The IDs are encoded into symbols utilizing the network IDs as seeds to scramble respective pilots that are then transmitted by utilizing the symbols. The pilots can be structured into a single OFDM symbol and/or multiple OFDM symbols. The single symbol

Power savings in hierarchically coded modulation

09/02/10 - 20100220816 - A wireless communication apparatus in a hierarchically coded modulation system can use error control mechanisms generated during decoding of base layer information to predict a probability of successful demodulation of enhancement layer information. Performance in the demodulation of the base layer correlates to performance in the demodulation of the enhancement
