Techniques for waveform compression

An user equipment (UE) for wireless communications, comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and operable to execute the code to cause the UE to:
• generate an input signal comprising information for transmission over a wireless channel;
• perform a first waveform shaping stage of a multistage waveform shaping process on the input signal, wherein performing the first waveform shaping stage comprises a first operation that increases an in-band emissions ratio of the input signal and a second operation, performed after the first operation, that reduces a peak-to-average-power ratio (PAPR) of the input signal;
• perform a second waveform shaping stage of the multistage waveform shaping process on an output of the first waveform shaping stage, wherein performing the second waveform shaping stage comprises reducing an adjacent channel leakage ratio of the output of the first waveform shaping stage after increasing the in-band emissions ratio of the input signal and reducing the PAPR of the input signal;
• and
• transmit a signal over the wireless channel, wherein the signal is based at least in part on an output of the second waveform shaping stage.

A non-transitory computer-readable medium storing code for wireless communication at a user equipment (UE), the code comprising instructions executable to:

• generate an input signal comprising information for transmission over a wireless channel;
• perform a first waveform shaping stage of a multistage waveform shaping process on the input signal, wherein performing the first waveform shaping stage comprises a first operation that increases an in-band emissions ratio of the input signal and a second operation, performed after the first operation, that reduces a peak-to-average-power ratio (PAPR) of the input signal;
• perform a second waveform shaping stage of the multistage waveform shaping process on an output of the first waveform shaping stage, wherein performing the second waveform shaping stage comprises reducing an adjacent channel leakage ratio of the output of the first waveform shaping stage after increasing the in-band emissions ratio of the input signal and reducing the PAPR of the input signal;
• and
• transmit a signal over the wireless channel, wherein the signal is based at least in part on an output of the second waveform shaping stage.
