Classification: CPC H  Y | IPC H

Claim 9:
10. A wireless communication apparatus comprising a processor and a memory storing instructions, execution of which by the processor causes the apparatus to:
determine, for an input sequence of coefficients that is generated by mapping data bits to constellation points according to a π/2-Binary Phase Shift Keying (BPSK) modulation scheme, an output sequence; and
generate a waveform using the output sequence;
wherein the output sequence corresponds to an output of a convolutional modulation between a three-coefficient function having values, 2
    
    2
  
  ,, 1, and, 2
  
  2, and an intermediate sequence,
wherein the intermediate sequence is generated by inserting a zero coefficient between each pair of adjacent coefficients of the input sequence,
wherein the convolutional modulation comprises a multi-path delay operation, and wherein the multi-path delay operation comprises:
generating multiple delayed sequences based on the intermediate sequence using different delay values; and
computing a weighted sum of the multiple delayed sequences using the three-coefficient function.
