Abstract
The disclosure relates to a processing module of a receiver device and associated method and apparatus. The method comprises receiving a signal comprising one or more frames, each frame comprising a synchronization-symbol-portion, a security-sequence-portion, and a data-payload-portion; and processing the signal to perform carrier recovery, and excluding at least part of the security-sequence-portions of the one or more frames from the carrier recovery process.
Claims17
A receiver comprising:
- a processor;
- and
- a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
- receiving a signal comprising one or more frames, each frame comprising a synchronization-symbol-portion, a security-sequence-portion with both a known security-sequence and an unknown security-sequence, and a data-payload-portion;
- inspecting a data-payload-portion of a frame with the unknown security-sequence to obtain data;
- using the obtained data to determine a target pattern for a security-sequence-portion of a subsequent frame;
- performing ranging on the subsequent frame using the known security-sequence of the frame;
- and
- performing a carrier recovery process on the signal, wherein at least part of the known security-sequence is included in the carrier recovery process and the unknown security-sequence is excluded from the carrier recovery process.
6 more elements
A system comprising:
- at least one receiver device configured to:
- receive a signal comprising one or more frames, each frame comprising a synchronization-symbol-portion, a security-sequence-portion with both a known security-sequence and an unknown security-sequence, and a data-payload-portion,
- inspect a data-payload-portion of a frame with the unknown security-sequence to obtain data,
- use the obtained data to determine a target pattern for a security-sequence-portion of a subsequent frame, perform ranging on the subsequent frame using the known security-sequence of the frame, and
- perform a carrier recovery process on the signal, wherein at least part of the known security-sequence is included in the carrier recovery process and the unknown security-sequence is excluded from the carrier recovery process;
- and
- at least one transmitter device configured to communicate with the at least one receiver device, generate a signal comprising one or more frames, each frame comprising a synchronization-symbol-portion, a security-sequence-portion with both a known security-sequence and an unknown security-sequence, and a data-payload-portion, wherein at least part of the known security-sequence is included in a carrier recovery process and the unknown security-sequence is excluded from the carrier recovery process.

A method for operating a receiver device, the method comprising:
- receiving a signal comprising one or more frames, each frame comprising a synchronization-symbol-portion, a security-sequence-portion with both a known security-sequence and an unknown security-sequence, and a data-payload-portion;
- inspecting a data-payload-portion of a frame with the unknown security-sequence to obtain data;
- using the obtained data to determine a target pattern for a security-sequence-portion of a subsequent frame;
- performing ranging on the subsequent frame using the known security-sequence of the frame;
- and
- processing the signal to perform carrier recovery, wherein at least part of the known security-sequence is included in the carrier recovery process and the unknown security-sequence is excluded from the carrier recovery process.
