Abstract EN
We propose a simpler and faster Gold codes generator, which can be efficiently initialized to any desired code, with a minimum delay.
Its principle consists of generating only one sequence (code number 1) from which we can produce all the other different signal codes.
This is realized by simply shifting this sequence by different delays that are judiciously determined by using the bicorrelation function characteristics.
This is in contrast to the classical Linear Feedback Shift Register (LFSR) based Gold codes generator that requires, in addition to the shift process, a significant number of logic XOR gates and a phase selector to change the code.
The presence of all these logic XOR gates in classical LFSR based Gold codes generator provokes the consumption of an additional time in the generation and acquisition processes.
In addition to its simplicity and its rapidity, the proposed architecture, due to the total absence of XOR gates, has fewer resources than the conventional Gold generator and can thus be produced at lower cost.
The Digital Signal Processing (DSP) implementations have shown that the proposed architecture presents a solution for acquiring Global Positioning System (GPS) satellites signals optimally and in a parallel way.
