Abstract
Method for receiving data packet transmissions, wherein synchronization with a transmitter is accomplished based on detection of a preamble transmitted by the transmitter. A time multiplexing scheduling of a single hardware receiver arrangement is used, and the time multiplexing scheduling has a main time slot comprising a first listen period and a second listen period following the first listen period. In the first listen period a first type of synchronization detection is executed (e.g. IEEE 802.15.4), and in the second listen period a second type of synchronization detection different from the first type of synchronization detection is executed (e.g. BLE).
Claims19
Method for receiving data packet transmissions, wherein synchronization with a transmitter is accomplished based on detection of a preamble transmitted by the transmitter,
- the method further comprising
- using a time multiplexing scheduling of a single radio receiver realized in hardware comprising a hard-limiting radio front end coupled to at least one antenna input, the time multiplexing scheduling having a main time slot comprising a first listen period having a first type of synchronization detection and a second listen period having a second type of synchronization detection different from the first type of synchronization detection with the second type of synchronization detection following the first listen period,
- wherein the time multiplexing scheduling is configured to detect the preamble and collect preamble symbols over a complete preamble period whenever the preamble extends from the first listen period into the second listen period and then to combine different received portions of the preamble that is repeated to form a full preamble that is used for synchronization with the transmitter.
