Performance analysis of concatenated Reed-Solomon and next generation polar codes for 6G communication systems.

Area of Science:

• Telecommunications Engineering
• Information Theory
• Error Correction Coding

Background:

• High data rate communication systems, like 6G, face challenges with burst errors degrading reliability.
• Existing 5G New Radio (NR) polar codes require enhancement to meet 6G's ultra-high reliability demands.

Purpose of the Study:

• To investigate the combination of Reed-Solomon (RS) codes with 5G NR polar codes for burst error correction in 6G systems.
• To evaluate the performance of serial and hybrid concatenated coding schemes.

Main Methods:

• Employed serial and hybrid concatenating methods for RS and 5G NR polar codes.
• Utilized sequential iterative hard decision decoding and Soft Input Soft Output (SISO) with Generalized Minimum Distance (GMD) decoding for the RS component.
• Evaluated Bit Error Rate (BER) and Block Error Rate (BLER) performance under burst error conditions.

Main Results:

• The concatenated RS-NR-Polar code achieved a BER of [Formula: see text] at -5.78 dB, outperforming the 5G NR polar code's [Formula: see text] BER at -2.79 dB by 3 dB SNR.
• Demonstrated superior performance in power-domain NOMA systems with inter-user interference.
• Deep Neural Network (DNN)-based GMD decoding further improved BER to [Formula: see text] at -6.78 dB compared to non-DNN SISO GMD.

Conclusions:

• The proposed RS-NR-Polar concatenated coding scheme effectively mitigates burst errors in 6G communication.
• This approach significantly enhances reliability and meets the stringent requirements for future 6G networks.
• The system shows promise for applications including power-domain NOMA and advanced decoding techniques.
