Abstract: A system and method for a single spatial stream based multiple-input multiple-output (MIMO) communication system in wireless MIMO channels with a non-zero mean or a fixed component is provided which utilizes deterministic beamforming in the transmitter and deterministic combining at the receiver. For transmission and reception of a data over MIMO channels, the method and system avoids the requirement of knowledge of the instantaneous channel values at the transmitter and the receiver. By assuming perfect knowledge of the mean value of the channel matrix at the transmitter, a beamforming vector is obtained for the transmitter. The receiver utilizes deterministic receive weights which are chosen using the channel statistics.

The heat from the inefficiency of the antenna is conducted to the heat to electricity conversion device. Additional heat from the transmitter electronics and any other inefficient processes can also be conducted to the heat to electricity conversion device. In this manner, the overall efficiency of the carbon nanotube antenna can be substantially increased.

Abstract: A method of secure erase of an electronic device that applies a predetermined voltage to a device. The voltage is selected to be high enough to quickly destroy all data cells of the electronic device, but not high enough to destroy lines to the data cells of the electronic device. Accordingly, since the voltage is too low to destroy the word or bit lines, the predetermined voltage is applied to every data cell using the word or bit lines such that all data is removed. The present invention has the advantage of quickly, reliably, and permanently removing all of the data from the electronic device. The predetermined high voltage can differ for different types of SSDs.

The wireless communication device may receive a selection that indicates a power or a signal processing functionality. The wireless communication device may then modify functions associated with a plurality of smart antennas based on the power or signal processing functionality and in relation to a reference design. The wireless communication device may then determine performance associated with the modified functions. The modified functions may, for example, include adjusting power of the smart antenna of the transmitter or receiver associated with the wireless communication device, adjusting power of the radio frequency (RF) chain of the transmitter or receiver associated with the wireless communication device, varying the number of antenna elements for transmissions or receptions, selecting a signal processing technique, or varying the power control algorithm.

Abstract: A system and method for generating weight values based on maximum data rate for weighting elements included within signal weighting and combining arrangements used in various multi-antenna transmitter and receiver structures is disclosed herein. Weighting values for a given signal combining arrangement are set so as to maximize an output data rate of the applicable multi-antenna system in the presence of adaptive bit loading of the subcarriers of a transmitted signal. The disclosed techniques may be employed to maximize a data rate of a multi-antenna communication system by using adaptive bit loading and RF and baseband weighting schemes. In this case a search is conducted over various combinations of RF and baseband weights in order to find the weight combination which, when adaptive bit loading is also employed, maximizes the data rate.
