Hi all, I'm trying to generating a square wave, the amplitude of each chip the square wave is coded by a 113-bit legendre code respectively. The following code is generating a source for legendre code: #ls 113-bit bits = (1,0,0,1, 0,0,0,1, 0,1,1,1, 1,0,1,0, 1,1,1,0, 0,1,0,1, 1,0,1,1, 0,1,0,0, 1,1,1,0, 1,0,1,1, 1,1,0,1, 0,0,0,1, 0,0,1,1, 0,1,0,1, 1,1,0,0, 0,1,0,0, 0,0,1,0, 0,1,0,0, 0,0,1,1, 1,1,1,0, 0,1,1,0, 0,1,1,1, 1,0,1,0, 0,0,1,0, 0,1,0,0, 0,0,1,0, 0,0,1,1, 1,0,1,0, 1) in_data = gr.vector_source_b(self._bits, True ) # Map to constellation constellation = [-1, 1] mapper = gr.chunks_to_symbols_bf(self._constellation) And the sig_source is used to generate a square wave : #generate square wave self.sqr = gr.sig_source_f(if_rate, gr.GR_CONST_WAVE, options.rate, options.amplitude,0) Is there any approach could code the amplitude of each chip of the square wave to be the source code? Looking forward to your help Thank you so much! Regards, Yan
