BER Performance Using Linear Phase Orthogonal Binary Codes for Multi-users Mobile Communication

Sequential logic circuit gold codes for electronics and communication technologies

“…The two maximum length sequences are grouped with the (2 n + 1) XOR gates, which constitute some set of (2 n + 1) gold code sequences. Linear feedback shift registers (LFSR) [6 , 7] consist of ‘n’ successive 2-state memory blocks or flip-flops (FFs) that are synchronized simultaneously by a clock. Every memory unit changes states simultaneously with the input clock pulses, and each clock pulse shifts the data from one memory block to the next.…”
