| 20120034952 | MULTIPLE-ANTENNA SYSTEM FOR CELLULAR COMMUNICATION AND BROADCASTING - A multiple-antenna system for use in cellular communication and broadcasting. The multiple-antenna transmission system can be controlled, adjusted, configured, or reconfigured to produce desirable radiation beam patterns suitable for different types of applications. A signal distribution network may be provided in the multiple-antenna system. The signal distribution network is embedded in a transmitter and controls the distribution of signals to one or more antennas in accordance with application requirements. Various antenna radiation patterns suitable for different applications can be generated by reconfiguring the connections and gain settings in the signal distribution network. For example, narrow beams may be generated for use in unicast applications, whereas sector beams may be generated for use in broadcast applications. Certain techniques may be employed to manage the transition from one type of transmission mode to another type of transmission mode. | 02-09-2012 |

| 20080304551 | Methods and Apparatus for Overlaying Multi-Carrier and Direct Sequence Spread Spectrum Signals in a Broadband Wireless Communication System - A broadband wireless communication system, wherein both Multi-Carrier (MC) and Direct Sequence Spread Spectrum (DSSS) signals are intentionally overlaid together, in both time and frequency domains. The overlaying mitigates the weaknesses of each technique. The MC signal carries the broadband data signal and takes advantage of its high spectral efficiency, while the DSSS signal is used for special purpose processing such as initial random access, channel probing, and short messaging, where properties such as signal simplicity, self synchronization, and performance under severe interference are desired. The methods and techniques ensure that the MC and the DSSS signals are both distinguishable and that the interference between the overlaid signals is minimized to have insignificant impact on the expected performance of either signal. | 12-11-2008 |
