Abstract

The telecommunications industry has evolved significantly, with advancements from 1G to 4G and now towards 5G, promising enhanced data speeds and connectivity. Orthogonal Frequency Division Multiplexing (OFDM) is crucial in this transition due to its efficient spectrum utilization and ability to handle frequency-selective fading. However, OFDM is susceptible to Carrier Frequency Offset (CFO), leading to Inter-Carrier Interference (ICI) and degraded performance. This research explores the integration of OFDM with Improved Sinc-power Pulse (ISP) and Convolutional Channel Coding to mitigate ICI and enhance system reliability in the 5G era. Using MATLAB simulations, we assessed the impact of CFO on OFDM systems with and without ISP pulse shaping and Convolutional Coding. Results showed that Convolutional Coding significantly improves performance by reducing ICI, achieving a Bit Error Rate (BER) of approximately 0.0018. ISP pulse shaping, combined with Convolutional Coding, effectively minimizes frequency offset effects and improves system performance, offering a robust solution for future wireless communication systems.
