Sequence generation for spread spectrum from signal sampling

A method for generating a spreading sequence, the method comprising:

• receiving a plurality of signals from a remote device;
• sampling the plurality of signals to generate a plurality of data sets corresponding to the plurality of signals, respectively, each data set indicating a power value of the corresponding signal;
• selecting, from the plurality of data sets, one or more data sets indicating a power value greater than a predetermined value;
• and
• generating a spreading sequence based on the one or more selected data sets.

A system comprising first and second devices, each of the first and second devices comprising:

• one or more processors;
• and
• memory in communication with the one or more processors, the memory comprising code that, when executed, causes the one or more processors to control the first or second device to:
• transmit a plurality of first signals from a first device to a second device;
• transmit a plurality of second signals from the second device to the first device;
• sample, at the second device, the plurality of first signals to generate a plurality of first data sets corresponding to the plurality of first signals, respectively, each first data set indicating a power value of the corresponding first signal;
• sample, at the first device, the plurality of second signals to generate a plurality of second data sets corresponding to the plurality of second signals, respectively, each second data set indicating a power value of the corresponding second signal;
• select, at the second device, from the plurality of first data sets, one or more first data sets indicating a power value greater than a first predetermined value;
• select, at the first device, from the plurality of second data sets, one or more second data sets indicating a power value greater than a second predetermined value;
• generate, at the second device, a first spreading sequence based on the one or more selected first data sets;
• and
• generate, at the first device, a second spreading sequence based on the one or more selected second data sets.

A method comprising:

• transmitting a plurality of first signals from a first device to a second device;
• transmitting a plurality of second signals from the second device to the first device;
• sampling, at the second device, the plurality of first signals to generate a plurality of first data sets corresponding to the plurality of first signals, respectively, each first data set indicating a power value of the corresponding first signal;
• sampling, at the first device, the plurality of second signals to generate a plurality of second data sets corresponding to the plurality of second signals, respectively, each second data set indicating a power value of the corresponding second signal;
• selecting, at the second device, from the plurality of first data sets, one or more first data sets indicating a power value greater than a first predetermined value;
• selecting, at the first device, from the plurality of second data sets, one or more second data sets indicating a power value greater than a second predetermined value;
• generating, at the second device, a first spreading sequence based on the one or more selected first data sets;
• and
• generating, at the first device, a second spreading sequence based on the one or more selected second data sets.
