This paper analyses foundational techniques for improving wireless communication systems, including coding methods, modulation schemes, and channel equalization. Using industry-standard simulation tools, the paper evaluates the performance of these techniques under different channel conditions. Convolutional codes, punctured and unpunctured, are assessed for reliable data transfer. The suitability of various modulation schemes, such as Phase Shift Keying (PSK) and Quadrature Amplitude Modulation (QAM), are examined. Linear and decision-feedback equalization techniques are evaluated for mitigating the effects of channel impairments. The paper provides practical insights into the implementation of these techniques, emphasizing their importance in modern wireless communication systems.
