Patent ID: 8369381

Claim:
A device for spread spectrum digital communication by Golay complementary sequence modulation, comprising: a processor; a memory; and wherein the memory contains instructions that, when executed by the processor, perform the following steps: receiving information comprising binary data for transmission through a communication channel, encoding and dividing said received binary data into symbols for spread spectrum transmission, modulating and encoding each symbol separately using Golay complementary sequences to generate a Golay sequence modulated binary data signal by (a) generating η binary Golay sequences and encoding each symbol of said received binary data with one of the η binary Golay sequences as entry data with low cross-correlation of the Golay sequences to generate an output signal, and (b) modulating said output signal with N-PSK modulation to generate the Golay sequence modulated binary data signal, using a double accumulator and shift register, including elements accumulating and displacing said sequences generated in order to obtain different phases, and transmitting said Golay sequence modulated binary data signal through said communication channel.
