| 20090116541 | Mitigating interference in a coded communication system - A technique weights noise power used in a demodulation/demapping process using on an estimate of interference and its associated power. Using this technique the effect of partial interference can be ameliorated. For example, a value, σ | 05-07-2009 |
| 20100080317 | SYMBOL MIXING ACROSS MULTIPLE PARALLEL CHANNELS - Symbol mixing across multiple input multiple output (MIMO) parallel channels is disclosed. Each data symbol is transmitted over an effective channel with a weighted sum of the singular values associated with all spatial channels. By averaging the singular values, there is less of a penalty associated with the choice of modulation and coding on the data symbols, since all transmitted symbols experience roughly the same signal to noise ratio (SNR) in transmission. | 04-01-2010 |
| 20100162075 | Low complexity LDCP decoding - A technique for low-density parity-check (LDPC) coding involves utilizing a fixed point implementation in order to reduce or eliminate reliance on floating point operations. The fixed point implementation can be used to calculate check node extrinsic L-value as part of an LDPC decoder in an LDPC system. The technique can include one or more of linear approximations, offset approximations, and node-limiting approximation. A system constructed according to the technique implements one or more of linear approximations, offset approximations, and node-limiting approximation. | 06-24-2010 |
| 20100214145 | SPUR CANCELLATION - A technique to mitigate in-band spurs introduced into a signal due to various board/SiP layout issues at a receiver is disclosed. The spurs can be approximated as sinusoids at different known frequencies with unknown amplitudes and phases. The technique is applicable to both single and multiple spur cancellation. | 08-26-2010 |
| 20100254325 | CHANNEL SELECTION AND INTERFERENCE SUPPRESSION - Several adaptive techniques are described to combat interference in multiple-input multiple-output (MIMO) systems. In addition to adaptive frequency selection, interference suppression techniques for a selected carrier frequency are presented. The interference suppression technique can be adaptively selected based on the availability and quality of channel state information (CSI) and interference statistics. Techniques to estimate interference statistics are also presented. Interference mitigation techniques are also presented for automatic gain control (AGC), intermittent interference, and interference caused to other networks. | 10-07-2010 |
| 20110060956 | INTERFERENCE-COGNITIVE TRANSMISSION - Interference cognitive devices are described. An interference cognitive device can be collocated with a transmitter of an interference cognitive transmitter (ICT), as receive chains or portions thereof at the ICT. An interference cognitive device can also be remote with respect to the transmitter, which operates in an interference cognitive network and receives data directly or indirectly from the interference cognitive device. The ICT uses the data to mitigate interference while continuing to operate in accordance with a performance metric. | 03-10-2011 |
| 20110110345 | MESSAGE ROUTING IN WIRELESS MESH NETWORKS - Disclosed are methods and apparatuses related to the routing of communications in a wireless mesh network so as to provide improved range, reliability and/or throughput. At least some aspects of the techniques and apparatuses can be implemented in an intermediary node (relay node) on a wireless mesh network. The relay node and other devices on the wireless network may implement a form of multiple-input multiple-output (MIMO) communication, such as multi-user MIMO (MU-MIMO). The devices on the network can communicate in accordance with IEEE standard 802.11. | 05-12-2011 |
