A wireless network includes a base station and a user equipment. The base station is configured to wirelessly transmit radio frequency (RF) signaling representing synchronization signal block (SSB) burst comprising a set of SSBs, each SSB associated with a different beam transmitted by the base station and having a corresponding index value representing a position of the SSB in the SSB burst. The user equipment is configured to detect an SSB of the SSB burst and to identify an index value of the SSB by iteratively performing a decoding process for a physical broadcast channel (PBCH) of the SSB, each performed iteration using a different index values selected from a prioritized ordering of the set of index values.

The present application relates to a receiver for performing a decimation on a signal for pattern detection and a method of operating thereof. A frequency-domain decimator component and a pattern detector component arranged at the receiver are provided. The frequency-domain decimator component is coupled to at least one antenna to receive an input sequence of samples of the signal received at the at least one antenna. The frequency-domain decimator component is further configured to apply an anti-aliasing filter and to decimate the input sequence. The frequency-domain decimator component is further arranged to output the input sequence filtered and decimated as output sequence. The pattern detector component is coupled to the frequency-domain decimator component to receive the output sequence. The pattern detection component is further configured to perform a pattern detection based on cross-correlation values in frequency domain between the output sequence and predefined patterns.

A conference call system comprises an input interface for receiving during a conference call at least two input streams of audio signal, each from another source. A selection unit is connected to the input interface, for selecting a number of dominant speaker streams out of the input streams, the number being less than or equal to a maximum number of dominant speakers value and each of the dominant speaker streams representing speech from a respective dominant speaker. A mixer is connected to the selection unit, for mixing the selected streams into an output stream. The conference call system comprises an output interface for outputting the output stream and a selection control unit connected to the selection unit and the input interface, for dynamically setting, during the conference call, the maximum number of dominant speakers value based on dynamics of the conference call.
