摘要： System and method for determining a separation between communicating devices. A preferred embodiment comprises a first device transmitting a signal over multiple subbands to a second device, the second device determining a timing for the signal by processing the signal in each subband separately. The second device then transmits a signal back to the first device along with timing information (again, over multiple subbands). The first device then determines a timing for the signal and by determining a difference in the timing information provided by the second device and timing information it determines, the first device can compute the separation between it and the second device. The use of multiple subbands can dedicate more bandwidth to the transmission of the signal, permitting greater resolution.

摘要： Embodiments of the invention provide methods for maximizing the bandwidth utilization in the uplink of a communication system supporting time division multiplexing between unicast and multicast/broadcast communication modes during transmission time intervals in the downlink of a communication system. This is accomplished by multiplexing at least unicast control signaling for UL scheduling assignments in TTIs supporting the multicast/broadcast communication mode. Moreover, multiplexing of unicast control signaling can also be accomplished by splitting a symbol of the multicast/broadcast TTI into two shorter symbols with the first of these two shorter symbols carrying at least unicast control signaling and the second of these shorter symbols carrying multicast/broadcast signaling.

摘要： A touch screen system includes a capacitive touch screen (1) including a plurality of row conductors (7-1,2 . . . n) and a column conductor (5-1). A plurality of cotemporaneous orthogonal excitation signals (S1(t), S2(t) . . . Sn(t)) are simultaneously driven onto the row conductors, respectively. The capacitively coupled signals on the column conductor may be influenced by a touch (10) on the capacitive touch screen. Receiver circuitry (50) includes a sense amplifier (21-1) coupled to generate an amplifier output signal (r1(t)) in response to signals capacitively coupled onto the column conductor. WHT-based circuitry (35) determines amounts of signal contribution capacitively coupled by each of the excitation signals, respectively, to the amplifier output signal.

摘要： A Hybrid Automatic Retransmission Request (H-ARQ) technique is provided for Multi-Input Multi-Output (MIMO) systems. The technique changes the basis (V) upon retransmission, which helps reduce the error probability upon retransmission. This basis hopping technique provides for improved performance gain without significant increase in design complexity. In one embodiment, communication device (100) includes a receiver section (114) for receiving an acknowledgment (ACK) or a non-acknowledgment (NACK) signal in response to information transmitted by the transmitter section of the communication device. If a NACK is received, a new basis is selected from a set of basis stored in a basis set unit (110). The new basis that is selected is then used by a linear transformation unit (106) in the retransmission of the information.
