Enhanced BER using Efficient APSK-TCM Approach for Future Wireless Communication System

In wireless communication system, the Bit Error Rate (BER) performance has been evaluated by key parameters to seek higher efficiency of communication channel. Those parameters are type of modulation and kind of channel coding which can be satisfied the quality of digital scheme and mitigate the multipath fading problems which are Inter Symbol Interference (ISI), and Inter Carrier Interference (ICI) between symbols. The new advanced modulation called Asymmetric Phase Shift Keying (APSK) connected with recent code called Trellis Code Modulation (TCM) can be increased the capably and accuracy of wireless communication system and used for the future Fifth Generation (5G) standard. APSK combines simultaneously two modulations using both the Amplitude and Phase Shift Keying (ASK and PSK). In addition, TCM code is a class of convolutional codes, adds redundancy by combining coding and modulation into a single operation. It is not required the reduction in data rate or expansion in bandwidth. APSK and TCM are advanced techniques that getting fast data rate, high performance, reducing the BER, dropping Peak to Average Power Ratio (PAPR), and rising achievable Signal to Noise Ratio (SNR). Consequently, TCM-APSK approach with multiple symbols are investigated by MATLAB codes and the results are confirmed that the TCM-APSK modulation with various rate will reach the perfect performance compared to original APSK. From the test results presented in this paper, M-APSK modulation attached with TCM code is efficiently mechanism that increased capacity, quality, and reliability of the improvable BER of wireless communication system by more than 60% than original APSK scheme. It is made the performance of wireless communication system more powerful of high data rate, less error and robust the system against the multipath fading Keywords - Asymmetric Phase Shift Keying (APSK), Trellis Code Modulation (TCM), Bit Error Rate (BER), Euclidean Distance (ED), Ring Ratio (α), Peak to Average Power Ratio (PAPR), Signal to Noise Ratio (SNR), Inter-Symbol Interference (ISI), Inter Carrier Interference (ICI).
