Abstract: Methods and systems are provided to generate digital coefficients for a filter. The generation of coefficients relies on a Fourier transformation of an impulse response in time domain that is zero padded, e.g., zeros are appended to an array corresponding to a sampled input signal of length M. A unit prototypical filter is generated through a frequency domain response of length NFFT = Ns+M-1, wherein NS is a sampling length of the incoming signal. The unit prototypical filter is then circularly shifted in order to generate a band pass filter centered at a desired frequency. Circularly shifted filters are point-to-point added to generate a set of composite digital coefficients to filter the incoming signal. The reference frequencies for the composite filter are extracted from a message received from one or more base stations associated with one or more service providers. The composite filter typically operates on a frequency repeater.

Abstract: A single, common correlation filter (CF) core is provided in a wireless system using CDMA (code division multiple access). A plurality of channels with different data rates are provided in the wireless system. The channels provided in the wireless system include the access channel, the maintenance channel, and the traffic channel in which information (e.g., pilot or data symbols or both) is transmitted at the tier 1 (which is the basic despreading rate), tier 2 and tier 3 rates. The data rate for transmitting the information is programmable by an external programmable processor, e.g., a digital signal processor (DSP). A user-unique code, such as a PN (pseudo-random noise) code, is applied to the information being transmitted in the channels of the wireless system. Theinformation is modulated and transmitted in any one of the channels at any data rate. The transmitted information is correlated at the basic despreading rate (i.e., the tier 1 rate) in the correlation filter (CF) of the wireless system by time multiplexing delayed versions of the PN code (or orthogonal code, Walsh code) to the correlation filter core. The correlated information is then demultiplexed and demodulated. The demodulated information is summed at the proper integer multiple of the tier 1 rate to achieve the tier 2 and tier 3 rates. One or more signal components are selected (in terms of the received power, signal-to-noise ratio or multipath width) in a window or time period for optimal information recovery. The selecting step can also be implemented according to a preprogrammed time alignment. Furthermore, outputs from the demodulated information can be provided and combined for temporal diversity. Spatial diversity is achieved by providing a plurality of antennas, and a plurality of receivers at a location and providing a single, common correlation filter at each of the plurality of antennas of the receivers in the wireless system.

Abstract: A transmitter (10) which includes a quadrature phase shift keying (QPSK) modulator (14), and a receiver (20) which includes a pilot correlation filter (PCF) (23), a data matching filter (DMF) (22), a timing recovery mechanism, a sampler (24), and a QPSK demodulator (26) are provided in a wireless communication system. The transmitter (10) transmits a frame of data symbols and pilot symbols (frame) to a receiver in a wireless system. The QPSK modulator (14) modulates the frame. At the receiver (20), the PCF (23) recovers the pilot symbols, whereas the timing recovery mechanism tracks the timing of the pilot symbols in the frame. The DMF (22) enhances the multipath response of the received frame at known time intervals of the pilot symbols, and output a plurality of enhanced peaks. The sampler (24) samples the multipath response of the received frame at each of the enhanced peaks. The QPSK demodulator (26) demodulates the sampled frame and recovers the data symbols using QPSK demodulation based on the sampled frame.

Abstract: A frequency translating repeater (250) for use in a time division duplex radio protocol communications system includes a processor (260), a bus (261), a memory (262), an RF section (264), and an integrated station device (264). An access point (210) is detected based on information transmitted frequency channels using a protocol. Detection is initiated automatically during a power-on sequence or by activating an input device such as a button. Frequency channels are scanned for a beacon signal and an access point chosen as a preferred access point based on a metric such as power level.
