Title: Word line driver circuit with reduced leakage
Inventor: DUDECK DENNIS E
IPC: G11C7/10
Filed: 2007-08-28
Abstract: A word line driver circuit for use in a memory array including multiple memory cells and multiple word lines coupled to the memory cells for selectively accessing the memory cells includes a driver adapted to generate a word line signal as a function of a first set of address signals received by the word line driver circuit. The circuit further includes a switching circuit having a plurality of output nodes, the output nodes connected to respective ones of the plurality of word lines, and having an input node connected to an output of the driver and adapted to receive the word line signal. The switching circuit is operative to direct the word line signal to a selected one of the word lines during a memory access as a function of at least one control signal. Between a given pair of memory accesses, the output nodes and the input node of the switching circuit are held to a same prescribed voltage level to thereby substantially eliminate a leakage current path in the switching circuit.

Title: Coded-bit scrambling for multi-stream communication in a mimo channel
Inventor: KIM BYOUNG HOON
IPC: H04B7/0413
Filed: 2005-08-26
Abstract: In one embodiment, a multi-input/multi-output system (100) includes a receiver (104), processor, coded bit scrambler (114), coded bit descrambler (130), and transmitter (102). The receiver (104) generates demodulated symbol streams corresponding to a received signal. The processor generates coded bit sequences from source bit streams when operating in a transmit mode and bit log-likelihood ratio sequences from the information bit streams when operating in a receive mode. The coded bit scrambler (114) scrambles the coded bit sequences to generate scrambled bit streams when in the transmit mode. The coded bit descrambler (130) descrambles the log-likelihood ratio sequences by a real-valued descrambling sequence when operating in the receive mode, and also removes the effect of a scrambling sequence. The transmitter (102) generates a transmit signal corresponding to the scrambled bit streams.

Title: Distributed mobile access point acquisition
Inventor: BALASUBRAMANIAN SRINIVASAN
IPC: H04W48/16
Filed: 2008-10-03
Abstract: Providing for distributed access point management for access to a mobile network is described herein. By way of example, an interface application maintained at a Femto cell base station (BS) can facilitate initial power up and/or acquisition for a Femto user terminal (UT). Upon start-up, a bootstrap process is utilized by the Femto cell to provision the UT with an SDL establishing at least one BS as high priority within a particular geographic area (GEO). Thus, when the Femto UT is within the GEO, the UT is more likely to acquire, camp on and/or handoff to the preferred BS. When outside the GEO, a serving access point can provision the Femto UT OTA with a custom SDL suited to another GEO having a different high priority access point. By implementing access point management at distributed access points, expensive network equipment can be mitigated or avoided.
