Data symbols detection unit for transmit/receive device, has sequence provisioning unit providing group of sequences, which are stepped higher than sequences in transmission side, where chips of respective sequences store different values

摘要

The detection unit has a sequence provisioning unit (25) designed for provisioning a group of sequences with a set of chips. The sequences are mapped to another group of sequences in a transmission side and are stepped higher than the latter sequences, where the chips stores values different from chips in the transmission side. A correlation unit (23) is connected with the provisioning unit and correlates a demodulated signal with the former sequence group. An evaluation unit (24) is connected with the correlation unit and derives the value of data symbol by evaluating the correlation results. Independent claims are also included for the following: (1) a transmit/receive device for a data transmission system including a detection unit for detecting data symbols in a demodulated signal (2) an integrated circuit for use in a transmit/receive device (3) a method of detecting data symbols in a demodulated signal.
