    摘要: A method for a wireless communication network is presented. In one embodiment, the method includes receiving, by a base station, information about one or more interfering base stations with respect to a communication channel used by a mobile station. The method includes sending silence requests to an interfering base station to reduce interference from that interfering base station with respect to the communication channel. The method further includes establishing communication with the mobile station via the communication channel.

    摘要: Methods for accelerating charge equilibrium in a non-volatile memory device using floating gate memory cells are disclosed. Memory devices and storage systems using charge equilibrium acceleration are also disclosed. In one such method, a programming pulse is applied to the word line to change an amount of charge stored on the floating gate of the memory cells being programmed. A reverse field pulse is then applied to the memory cell using only voltages greater than or equal to about 0 volts. The reverse field pulse accelerates charge equilibrium by moving any electrons trapped in the insulating oxide layers to a stable location so that the threshold voltage is stabilized. After the reverse field pulse, a program verify operation is performed and additional programming pulses and reverse field pulses are applied as needed to properly program the memory cell.

    摘要: A method and communication system for selecting a mode for encoding data for transmission in a wireless communication channel between a transmit unit and a receive unit. The data is initially transmitted in an initial mode and the selection of the subsequent mode is based on a selection of first-order and second-order statistical parameters of short-term and long-term quality parameters. Suitable short-term quality parameters include signal-to-interference and noise ratio (SINR), signal-to-noise ratio (SNR), power level and suitable long-term quality parameters include error rates such as bit error rate (BER) and packet error rate (PER). The method of the invention can be employed in Multiple Input Multiple Output (MIMO), Multiple Input Single Output (MISO), Single Input Single Output (SISO) and Single Input Multiple Output (SIMO) communication systems to make subsequent mode selection faster and more efficient. Furthermore the method can be used in communication systems employing various transmission protocols including OFDMA, FDMA, CDMA, TDMA.
