Abstract

The exemplary embodiments of the present invention relate to a transmission part ( 500 ), to a receiver part ( 600 ), to a transceiver comprising the transmission and receiver parts, to a radio base station comprising the transceiver, to a method in the transmission part ( 500 ) and to a method in a receiver part ( 600 ). According to the embodiments of the present invention, the transmission part ( 500 ) is configured to generate calibration sequences; process the sequences to determine a resulting calibration signal prior to transmission to a receiver part for enabling the receiver part to detect group delay of the received resulting calibration signal for calibration of the transceiver and/or of the radio base station in a wideband communications system.

First claim

The invention claimed is:

1. A transceiver for a radio base station of a wideband communication system, wherein said transceiver is configured to detect a group delay for performing calibration and comprises a transmission part that includes a circuit that is configured to:
split an available system bandwidth into multiple, J, groups of contiguous subcarriers, each group of contiguous subcarriers representing a subband of the available bandwidth;
generate, for each subband, a co…
