Wireless Communication Systems: Modulation, Protocols Analysis

This assignment delves into various aspects of wireless communication, starting with the conversion of binary data into analog waveforms using different modulation techniques such as Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), Phase Shift Keying (PSK), and Differential Phase Shift Keying. It further explores the computation of frequency assignments for different data combinations, along with drawing approximate waveforms for analog and frequency modulation. The assignment includes a 16 QAM constellation diagram and explains the error detection process using Cyclic Redundancy Check (CRC), including a computation example. Additionally, it covers Direct Sequence Spread Spectrum, compares infrastructure and ad-hoc modes in WLAN, and contrasts the TCP and OSI protocol models. Finally, it addresses why hexagonal-shaped cells are preferred over square or circle shapes in cellular communications, providing a comprehensive overview of key wireless communication concepts.
