Title: Data transmission method, and a cellular radio system

Abstract: a data transmission method in a cellular radio system is provided. Each cell in a cellular radio system includes at least one base station and a number of subscriber terminal equipment connected to the at least one base station. A transmitter includes a mechanism for multiplying a signal of each user by a plurality of pseudorandom sequences. To enable high spectral efficiency and advantageous interference cancellation, a transceiver is provided which includes a mechanism for multiplying a signal of a user by a plurality of pseudorandom sequences. The transmitter further includes a mechanism for transmitting signals of different users multiplied by a same one of the pseudorandom sequences, distinguished from each other by use of time division.
