Telecommunication Assignment 2: Modulation, Protocols, WLAN, CRC, QAM

This document presents a comprehensive solution to a Telecommunication assignment, addressing various aspects of digital communication. The solution includes the conversion of binary data into analog waveforms using different modulation techniques such as ASK, FSK, PSK, and QAM. It also involves the computation of frequency assignments for different bit combinations, along with the generation of analog and frequency modulation waveforms. Furthermore, the assignment covers the creation of a 16 QAM constellation diagram, explanation of the Cyclic Redundancy Check (CRC) error detection process, and computation of frame check sequences. The solution also differentiates between Infrastructure and ad hoc modes in WLAN, compares TCP and OSI protocols for wired and wireless LANs, and explains the appropriateness of hexagonal-shaped cells in cellular communication. References are also included to support the solution.
