    Abstract: A write circuit for providing distinctive write currents to a chalcogenide memory cell is disclosed. The write circuit includes a current amplitude trim module, a current amplification and distribution module, and a write current shaping module. The current amplitude trim module provides a well-compensated current across a predetermined range of temperatures, voltage supplies and process corners intended for programming a chalcogenide memory cell. The current amplification and distribution module amplifies the well-compensated current in order to meet a programming requirement of the chalcogenide memory cell. The write current shaping module supplies an appropriate amount of write “0” current or write “1” current, based on the amplified current, to program the chalcogenide memory cell accordingly.

    Abstract: A method and apparatus for estimating and reporting the quality of a wireless communication channel between a wireless transmit/receive unit (WTRU) and a Node-B. A modulated signal is received from the Node-B over the communication channel and a channel estimation is performed on the modulated signal to provide a channel estimate. In one embodiment, the modulated signal is demodulated based on the channel estimate to provide a demodulated signal and a signal-to-interference (SIR) estimate based on the demodulated signal is obtained. The quality of the communication channel is estimated based on at least the SIR estimate. In an alternate embodiment, a SIR estimate based on the channel estimate is obtained. The quality of the communication channel is estimated based on the SIR estimate and additional information including at least one of delay spread, transmit power and WTRU velocity information.

    Abstract: An improved receiver and method estimate one or more parameters, such as amplitude and signal-to-noise ratio, of a received signal, such as an M-QAM or q-ASK signal. The amplitude of an M-QAM signal is estimated based upon known or ascertainable phase information regarding a plurality of transmitted symbols. The amplitude of a q-ASK signal is estimated based upon known or ascertainable magnitude information regarding a plurality of transmitted symbols. In another embodiment, the amplitude of an M-QAM or q-ASK signal is estimated based on statistical knowledge of the amplitude of the transmitted symbols. Other embodiments estimate amplitude, noise power, and signal-to-noise ratio of a received signal utilizing second-order and fourth-order moments of received samples, a maximum likelihood searching process, or a Kurtosis estimation process.
