摘要： K data signals, or bursts, are transmitted over a shared spectrum in a code division multiple access communication format. A combined signal is received and sampled over the shared spectrum, as a plurality of received vector versions. The combined signal includes the K transmitted data signals. A plurality of system matrices and an associated covariance matrix using codes and estimated impulse responses of the K data signals is produced. Each system matrix corresponds to a received vector version. The system and covariance matrices are extended and approximated as block circulant matrices. A diagonal matrix of each of the; extended and approximated system and covariance matrices are determined by prime factor algorithm—fast Fourier transform (PFA-FFT) without division of the matrix. The received vector versions are extended. A product of the diagonal matrices and the extended received vector versions is taken. An inverse block discrete Fourier transform is performed by a PFA-FFT on a result of the product to produce the estimated data of the K data signals.

摘要： Data is estimated from a received vector comprising a plurality of communications. A received wireless signal is converted to a baseband signal, which is sampled to produce a received vector. Channel responses are estimated for the received communications. The noise variance is estimated. The noise variance is scaled by a scaling factor. Samples are processed using the estimated channel responses and the scaled noise variance to produce a spread data vector. The spread data vector is despread to recover the data of the received wireless signal.

摘要： A method and apparatus for reducing the processing rate when performing chip-level equalization (CLE) in a code division multiple access (CDMA) receiver which includes an equalizer filter. Signals received by at least one antenna of the receiver are sampled at M times the chip rate. Each sample stream is split into M sample data streams at the chip rate. Multipath combining is preferably performed on each split sample data stream. The sample data streams are then combined into one combined sample data stream at the chip rate. The equalizer filter performs equalization on the combined sample stream at the chip rate. Filter coefficients are adjusted by adding a correction term to the filter coefficients utilized by the equalizer filter for a previous iteration.

摘要： A code indexing system for a CDMA communication station that uses orthogonal variable spreading factor (OVSF) codes having a single number mapped to each code. The new code number itself not only provides the code signature, but it is also used for the OVSF code generation. In addition, the system provides easy and fast generation of the available code list without the help of look-up table. This capability improves the dynamic code assignment.

摘要： A method and apparatus for scheduling transmissions via an enhanced dedicated channel (E-DCH) are disclosed. A scheduled power is calculated for scheduled data flows. A remaining transmit power is calculated for the E-DCH transmission. A rate request message is generated, wherein the scheduled power, remaining transmit power and rate request message are used to select transport format combinations (TFCs) and multiplex data scheduled for the E-DCH transmission. The remaining transmit power is calculated by subtracting from a maximum allowed power the power of a dedicated physical data channel (DPDCH), a dedicated physical control channel (DPCCH), a high speed dedicated physical control channel (HS-DPCCH), an enhanced uplink dedicated physical control channel (E-DPCCH) and a power margin.

摘要： A hybrid orthogonal frequency division multiple access (OFDMA) system including a transmitter and a receiver is disclosed. The transmitter includes a first spread OFDMA subassembly, a first non-spread OFDMA subassembly and a first common subassembly. The first spread OFDMA subassembly spreads input data and maps the spread data to a first group of subcarriers. The first non-spread OFDMA subassembly maps input data to a second group of subcarriers. The first common subassembly transmits the input data mapped to the first and second group of subcarriers using OFDMA. The receiver includes a second spread OFDMA subassembly, a second non-spread OFDMA subassembly and a second common subassembly. The second common subassembly processes received data to recover data mapped to the subcarriers using OFDMA. The second spread OFDMA subassembly recovers the first input data by separating user data in a code domain and the second non-spread OFDMA subassembly recovers the second input data.

摘要： A wireless communication system and method generates and shapes one or more three-dimensional control channel beams for transmitting and receiving signals. Each three-dimensional beam is directed to cover a particular coverage area and beam forming is utilized to adjust bore sight and beam width of the three-dimensional beam in both azimuth and elevation, and the three-dimensional control channel beam is identified. In another embodiment, changes in hot-zones or hot-spots, (i.e., designated high volume user coverage areas), are managed by a network cell base station having at least one antenna. Each of a plurality of wireless transmit/receive units (WTRUs) served by the base station use a formed beam based on one or more beam characteristics. When the coverage area is changed, the base station instructs at least one of the WTRUs to change its beam characteristics such that it forms a return beam concentrated on the antenna of the base station.
