Abstract: Disclosed are a sequence generation method, a sequence generation apparatus and a non-transitory computer-readable storage medium. The sequence generation method may include generating a first sequence according to a pre-generated random sequence, and using the first sequence as a reference signal sequence. The first sequence has a plurality of elements which are all in a form of complex numbers and have a same modulus value, a phase difference between two adjacent elements is less than π/2, and the modulus value is an amplitude value indicating signal strength.

Abstract: Methods, apparatus, and systems for reducing Peak Average Power Ratio (PAPR) in signal transmissions are described. In one example aspect, a wireless communication method includes determining, for an input sequence of coefficients, an output sequence and generating a waveform using the output sequence. The output sequence corresponds to an output of a convolutional modulation between a three-coefficient function associated with

Abstract: This disclosure relates generally to wireless communications and, more particularly, to systems and methods for modulating user data with conjugate data for time domain communications. In one embodiment, a method performed by a device includes: modulating user data into modulated user data elements; determining conjugate data elements, wherein each conjugate data element is a conjugate or opposite conjugate of different modulated user data elements; and transmitting, over a time domain, a user data sequence comprising the modulated user data elements interleaved with the conjugate data elements.

Abstract: Methods, apparatus, and systems for reducing Peak Average Power Ratio (PAPR) in signal transmissions are described. In one example aspect, a wireless communication method includes determining, for an input sequence, an output sequence corresponding to an output of a convolutional modulation between a plurality of values and an intermediate sequence. The intermediate sequence is generated by inserting a set of coefficients between coefficients of the input sequence. Each non-zero coefficient of the set of coefficients is inserted between a first adjacent coefficient and a second adjacent coefficient. Each non-zero coefficient has a power that is between a first power of the first adjacent coefficient and a second power of the second adjacent coefficient and a phase value between a first phase value of the first adjacent coefficient and a second phase value of the second adjacent coefficient. The method also includes generating a waveform using the output sequence.

Abstract: Methods, apparatus, and systems for reducing Peak Average Power Ratio (PAPR) in signal transmissions are described. In one example aspect, a wireless communication method includes determining, for a time-domain sequence x(i), an output sequence s(k). The output sequence s(k) is an inverse Fourier transform of a frequency-domain sequence S(j), and S(j) represents a dot-multiplication of a frequency-domain sequence Y(j) corresponding to the time-domain sequence x(i) and a frequency-domain sequence Z(j) corresponding to a three-coefficient function associated with

Abstract: A data modulation method, a communication device and a storage medium are disclosed. The data modulation method includes, performing a preset modulation operation on B consecutive data blocks, and configuring the B consecutive data blocks to have a same head-end reference signal sequence and/or a same tail-end reference signal sequence, inserting Z zeros between adjacent time domain data of the B consecutive data blocks; performing a filtering operation on the B consecutive data blocks into which Z zeros have been inserted, and transmitting the filtered data on a physical resource, where B is greater than or equal to 2 (i.e., B≥2), and Z is greater than or equal to 0 (i.e., Z≥0).

In one example aspect, a wireless communication method includes determining, for an input sequence, an output sequence. The output sequence corresponds to an output of a convolutional modulation between a set of coefficients and an intermediate sequence. The intermediate sequence is generated by inserting N zero coefficients between coefficients of the input sequence. The number of non-zero coefficients in the set of coefficients is based on N, N being a positive integer. Values of the non-zero coefficients correspond to values between 0 to π/2 to reduce a peak to average power ratio of the output sequence. The method also includes generating a waveform using the output sequence.
