    摘要: Systems and methods for generating a control signal for automatic wireless network version detection of a transmission. The control signal enables a receiver to detect the wireless network version detection of the transmission, so that the proper wireless network version is used for interpreting signaling information and decoding of the payload of the transmission. In some examples, the control signal is within a preamble of the transmission. The wireless network version can be an IEEE 802.11 version, such as proposed IEEE 802.11be. The control signal is compatible with legacy systems and can indicate the legacy signaling information by way of a Legacy Signal (SIG) (L-SIG) symbol. In some examples, the control signal can indicate the wireless network version by using an identifier symbol which is generated from at least part of, but is not identical to, the L-SIG symbol.

    摘要: According to an example aspect of the present disclosure, there is provided an apparatus comprising memory configured to store a set of probabilities of transitions between modulation symbols, the set of probabilities corresponding to a lower peak-to-average power ratio than a set of equal probabilities of transitions between modulation symbols, distribution matcher circuitry configured to process an input bit sequence into a symbol sequence, wherein frequencies of transitions between symbols in the symbol sequence conform to probabilities in the set of probabilities, a channel coder configured to generate parity bits of unity and negative unity from bit information obtained from the symbol sequence, grouping circuitry configured to assign symbols of the symbol sequence into groups each comprising two or more symbols, and multiplication circuitry configured to multiply each one of the groups with a corresponding one of the parity bits.

    摘要: A digital receiver being adapted for receiving an MSK modulated signal, comprises a digital front-end unit (10) adapted for providing samples having a phase value (θmeasure) of a down-mixed signal, a phase compensation unit (11) adapted for compensating the phase value (θmeasure) by delivering a phase offset compensated sample having a phase value (θsync), and a coherent demodulator (12) adapted for recovering information content from the phase offset compensated sample. The phase compensation unit (11) is adapted for analyzing a phase value (θsync) of the phase offset compensated sample, calculating a phase offset value (θoffset) based on the phase value (θsync) of the phase offset compensated sample, and applying the phase offset value (θoffset) when delivering a subsequent phase offset compensated sample.
