    Abstract: A heat dissipation assembly includes a heat sink, a retention module and a clip for securing the heat sink to the retention module. The heat sink includes a base for contacting with a heat generating device. The retention module includes a bottom wall and a first sidewall defining a slot therein and extending from the bottom wall. The clip includes a connecting portion pivotably connected to the retention module. The heat sink rests on the bottom wall of the retention module with an end thereof fitting in the slot, and an opposite end thereof being pressed by the clip. The clip can be in a released position that the clip is pivotable, so that the heat sink is removable from the retention module, and a locked position that the clip presses the heat sink. Thus, the heat sink can be secured to the heat generating device expediently.

    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: In a coding system for asymmetric digital subscriber line (ADSL) communications, a method of encoding a sequence of information bits is provided comprising the steps of dividing the information bits into encoding bits and parallel bits; encoding the encoding bits to produce encoded bits; mapping the encoded bits and the parallel bits into first and second pulse amplitude modulation (PAM) signals; and generating a quadrature amplitude modulation (QAM) signal from these first and second PAM signals. This method overcomes the decoder complexity that would otherwise be required due to the large QAM constellations involved for ADSL communications.

    Abstract: A receiver comprises a plurality of antenna elements for receiving a data signal. Each antenna element has a plurality of Rake fingers. Each Rake finger processes a received multipath component of the received data signal of its antenna element by applying a complex weight gain to that received multipath component. A complex weight gain generator determines the complex weight gain for each Rake finger for each antenna element using an input from all the Rake fingers. A summer combines an output of each Rake finger to produce an estimate of the data signal.

    Abstract: A read/write circuit for accessing chalcogenide non-volatile memory cells is disclosed. The read/write circuit includes a chalcogenide storage element, a voltage limiting circuit, a current-to-voltage converter, and a buffer circuit. The voltage limiting circuit, which is coupled to the chalcogenide storage element, ensures that voltages across the chalcogenide storage element will not exceed a predetermined value during a read operation. During a read operation, the current-to-voltage converter, which is coupled to the voltage limiting circuit, converts a current pulse read from the chalcogenide storage element to a voltage pulse. By sensing the voltage pulse from the current-to-voltage converter, the buffer circuit can determine a storage state of the chalcogenide storage element.
