The code rate of GPS L1C signals and BDS B1C signals is 1.023 Mbps, plus the proposed universal code generator has a code rate of 33 Mbps. Consequently, the proposed code generator has the least hardware complexity by removing redundant hardware with out affecting the general technique functionality. 6. Conclusions This paper proposed an area-efficient universal code generator for GPS L1C signals and BDS B1C signals. Previously, MB UCG [14,15] stored all the PRN codes by signal, channel, and satellite within the ROM, major towards the largest hardware complexity. To mitigate the large hardware complexity, LG UCG [16] generates the Legendre sequences on the fly and stores the generated Legendre sequences within the RAM. Primarily based on the stored Legendre sequences in the RAM, the PRN codes are generated. When compared with MB UCG [14,15], LG UCG [16] saves hardware by creating the Legendre sequence around the fly. However, LG UCG [16] demands important hardware complexity because of the use of RAM. Not too long ago, WG UCG [17] has generated PRN codes with Legendre sequences of ROM rather than RAM. By using the traits of ROM, the hardware complexity and initialization time for the RAM are lowered. Ultimately, the main notion in the proposed universal code generator should be to apply a Bomedemstat medchemexpress time-multiplexing method to the previous universal code generator so that you can save the typical hardware resources. The proposed structure shares the popular hardware according to the scheduling of a time unit rather than using the same hardware in the identical time by duplicating the same hardware. Though time multiplexing can reduced the hardware complexity in the price of rising the latency, the proposed code generator is very carefully made in order not to degrade the system performance. Because of the synthesis utilizing the CMOS 65 nm process, the proposed code generator has an region reduced by 98 , 93 , and 60 in comparison with the memory-based universal code generator [14,15], the Legendre-generation universal code generator [16], along with the Weil-generation universal code generator [17], respectively. Amongst the existing GNSS signals, as shown in Table 1, the proposed universal code generator can help only GPS L1C and BDS B1C signals since the two GNSS signals are primarily based around the Legendre sequence. On the other hand, it might be seamlessly extended if Legendre sequence-based codes are added for the GNSS within the future irrespective of the RF band.Author Contributions: Conceptualization, H.Y.; methodology, J.P. and H.Y.; software, J.P.; validation, J.P. and H.Y.; formal analysis, J.P. and H.Y.; investigation, J.P., M.K. and G.J; sources, J.P., M.K. and G.J.; information curation, J.P., M.K. and G.J.; writing–original draft preparation, J.P.; writing–review and editing, J.P. and H.Y.; visualization, J.P.; supervision, H.Y.; project administration, H.Y.; funding acquisition, H.Y.
