摘要： In a wireless network, a primary synchronization signal and a secondary synchronization signal are sent at a predetermined bandwidth in a transmission. The predetermined bandwidth is a lowest operating bandwidth of the wireless network. Data is also sent in the transmission using an operating bandwidth greater than the lowest operating bandwidth.

摘要： The transport format (TF) of a signal may be blindly detected from a reduced set of TF hypotheses. In an example embodiment, a method for the blind detection of a TF of a signal includes filtering a set of transport format hypotheses to identify a reduced set of TF hypotheses using one or more filtering schemes. From the reduced set of TF hypotheses, a TF that is associated with an interfering signal is detected. The TF includes a modulation and a spreading factor for the interfering signal. It may also include a number of channelization codes. In an example implementation, when an interfering signal is to be canceled, symbols carried by the signal are detected using the detected TF. Example filtering schemes include filtering based on system design/operation, filtering based on known configuration information, filtering based on an expected level of interference contribution, and so forth.

摘要： A transmitting apparatus includes a first OFDM modulator that generates a first OFDM modulation signal by modulating a first information signal using a first modulation scheme, the first OFDM modulation signal having a plurality of subcarriers. A second OFDM modulator generates a second OFDM modulation signal by modulating a second information signal using the first modulation scheme, the second OFDM modulation signal having a plurality of subcarriers, and that generates a third OFDM modulation signal by changing a second position in an in-phase quadrature-phase plane in which a signal point of the second OFDM modulation signal is positioned, to a third position, the third position being different from a first position in the in-phase quadrature-phase plane in which a signal point of the first OFDM modulation signal is positioned. A multiplexer generates a multiplexed signal to be transmitted in a common frequency band, by multiplexing the first OFDM modulation signal and the third modulation signal. A transmitter transmits the multiplexed signal.

摘要： In a communication station, such as a UE or Node B of a 3GPP system, where channelization coded signals are received on physical channels of at least one coded composite transport channel (CCTrCh) within timeslots of a system time frame, the actual number of channelization codes transmitted for the CCTrCh within a system time frame is determined. The transmitted channelization codes are then identified by performing a channelization code identification algorithm based on the determined number.

摘要： A data transmission method in which a CDMA-coded data signal is transmitted between a transmitter and a receiver in the form of a data stream of spread data bursts, with hierarchical CDMA codes used for transmission. Spread data is detected in a first step according to a mother code of at least one receiving code. The detected data is despread in a second step by despreading it using at least one generator. The detection process is aborted in a third step if the data has been despread to a sufficient extent, or, if this is not the case, the second step is repeated using the data last despread until the data has been despread to a sufficient extent.
