1. A wireless communication method, comprising:
determining, for an input sequence, an output sequence, wherein the output sequence corresponds to an output of a convolutional modulation between a set of coefficients and an intermediate sequence, wherein the intermediate sequence is generated by inserting N zero coefficients into the input sequence, wherein the set of coefficients includes non-zero coefficients that are represented as [f(0), f(1), . . . , f(2N)] or [f(0), f(1), . . . , f(2N+1)], wherein a number of the non-zero coefficients in the set of coefficients is 2N+1 or 2N+2, N being a positive integer indicating a number of zero coefficients inserted into the input sequence to generate the intermediate sequence, wherein values of the non-zero coefficients are based on cos (θi), and wherein i is between 0 and N and θi is between 0 to π/2 and a number of different values of cos (θi) for the set of coefficients is N+1; and generating a waveform using the output sequence.
