摘要:
The present invention is a dual-level flash memory cell design that stores 3 or more bits of information per transistor. The dual-level memory cell stores two lower bits in a first level and stores an upper bit in a second level. The lower bits are programmed, erased and read by alternate modes of operation wherein active regions operate as source and drain, and then drain and source. The upper bit is programmed and erased independent of the lower bits. However, reading of the upper bit depends upon read values of the lower bits. Additional levels are employed to store more than 3 bits of information.

The disclosure discloses a Software Defined Radio (SDR)-based radio communication transmission system. A front-end analog interface unit, a Digital-to-Analog (D/A) and Analog-to-Digital (A/D) conversion unit, a core processing unit and a storage unit adopt the universal bus for interconnection and interworking. The core processing unit is configured to acquire the front-end processed data from the front-end analog interface unit, and to choose to transmit the front-end processed data to the D/A and A/D conversion unit by the control of the universal bus according to whether the radio communication standard of the current data accords with the current working mode. The disclosure further discloses an SDR-based radio communication transmission method, which includes that: the core processing unit chooses to transmit the front-end processed data to the D/A and A/D conversion unit by the control of the universal bus according to whether the radio communication standard of the current data accords with the current working mode. The system and method of the disclosure can adapt to the coexistence of multiple radio communication standards and complement the advantages of each structure at the same time.

A technique for channel sounding in a wireless communication system includes determining respective geometries of multiple subscriber stations with respect to a serving base station. Respective time periods for sounding a channel between the multiple subscriber stations and the serving base station are then set based on the respective geometries of the multiple subscriber stations.

Methods and corresponding systems for reducing a peak-to-average signal ratio include determining peak and null samples of a symbol. Thereafter, an error signal is calculated that is responsive to the peak and null samples. In one embodiment the error signal has values corresponding to differences between the peak samples and a high threshold and the null samples and a low threshold. In response to the error signal, the samples are filtered to produce a filtered symbol having a reduced peak-to-average signal ratio. The error signal can also be used to calculate reserved tones on reserved subcarriers, which are combined with multi-tone subcarriers in a multi-carrier transmitter.

Grip pressure is monitored by a collection of battery powered components embodied in an assembly analogous to an ordinary wrist watch, that is a watch housing or casement and a stretchable band. The system, which we shall refer to as a swing monitor, is worn on the wrist and deployed in such a way that the back of the housing or casement is cinched securely to the back or underside of the wrist. A pressure plate on the back of the watch makes contact with the pulse region of the wrist. The flexing and relaxing of the muscles and tendons of the wearer is read by an electronic pressure sensing device, a piezo sensor. A tighter grip will register greater pressure and a looser grip, less pressure. The device records grip pressure associated with the swing of a golf club, tennis racquest or baseball bat, among other articles of sports equipment meant to be swung. The grip pressure determined to be optimal, that is giving the desired result, can be SAVED in the memory of the swing monitor system. Subsequent swings and their associated grip pressures are compared with the SAVED value of the optimal or best swing. An audible signal alerts the wearer if the grip pressure departs from that registered on the optimal or best swing.

A technique of operating a wireless communication system includes determining respective geometries of multiple subscriber stations, which include a first subscriber station and a second subscriber station, with respect to a serving base station. Respective channel sounding bandwidths for sounding the channel between the multiple subscriber stations and the serving base station are then scheduled, based on the respective geometries. The respective channel sounding bandwidths include a first channel sounding bandwidth (associated with the first subscriber station) and a second channel sounding bandwidth (associated with the second subscriber station). The first channel sounding bandwidth is greater than or equal to the second channel sounding bandwidth and the first subscriber station has a lower geometry than the second subscriber station.
