摘要： The invention relates to a data transmission method used in a CDMA-type radio system. A base station and terminal equipments exchange data at least in a packet switched mode, and a terminal equipment transmits to the base station on a random access channel a random access signal comprising at least a preamble (100) and a data part (102) multiplied by a spreading code. A predetermined set of spreading codes and signature sequences (104) are stored in the terminal equipment, and each signature sequence (104) determines one spreading code. The terminal equipment selects one signature sequence (104) by a random process from the set of signature sequences and adds the selected signature sequence (104) to the preamble (100) of the random access signal. Further, the terminal equipment uses the spreading code corresponding to the selected signature sequence (104) in the data part (102) of the random access signal. Interference cancellation is performed at the base station according to the signature sequence (104) of the preamble (100) of the received random access signal, such that at least the interference caused by the received data part (102) is eliminated from at least one other received signal in order to improve detection.

摘要： The invention relates to a method of implementing macrodiversity in a cellular radio network having in each cell at least one base station which communicates with subscriber terminals within its area. Packet switched connections are provided between the base station and the terminals, the connections comprising an actual traffic channel and a separate control channel. In signal transmission, the terminals use IQ modulation in which the traffic and control channels are multiplexed to be transmitted on different branches, and the terminals can communicate with more than one base station simultaneously. To enable macrodiversity in packet switched connections, the actual traffic channel connection is also maintained between the terminal and only one base station, and the control channel connection is maintained between the terminal and more than one base station simultaneously.

摘要： A method for reducing interference and a radio system where a signal spreadcoded by digital pseudo noise is used for communication are provided. As the delay distribution of the signals of subscriber terminal equipment at base stations is great and thus the mutual interference of the signals may also be great, the base station adjusts the phase of the spreading codes of the subscriber terminal equipment so as to reduce interference. The method and the radio system enable high data rates and reduce the calculation required for interference correction.

摘要： The invention relates to a reception method and a receiver in a system comprising in each cell a base station communicating with terminals located in its area. A received signal comprises a sum signal of signals originating from several transmitters. The receiver comprises means for performing interference elimination and a simultaneous multi-user detection to the signal and means for searching signal parameters. In order to reduce the required computational capacity, the receiver further comprises means for removing the effect of the signals of the known users from the receives sum signal, and means for estimating the parameters of the unknown signals from a narrowband residual signal.

摘要： A method and circuitry for channel estimation in a cellular communication system is disclosed. Data is transmitted with variable data transmission rates as a plurality of data symbols over a sequence of time slots. Each time slot has at least a proportion containing data symbols, the proportion being dependent on the data transmission rate. An estimate of the transmission rate is determined and is used in channel estimation so that the channel estimation is based on the proportion of received data symbols.
