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 two-level and four-level Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), Phase Shift Keying (PSK), and Differential Phase Shift Keying (DPSK). It computes frequency assignments for different data combinations, illustrates analog and frequency modulation waveforms, and presents a 16 QAM constellation diagram. The assignment also explains and draws the error detection process for Cyclic Redundancy Check (CRC) and computes the frame check sequence for given information. Furthermore, it discusses the transmitted signal using Direct Sequence Spread Spectrum and differentiates between infrastructure and ad hoc modes in WLAN, highlighting their communication paradigms and physical requirements. The document concludes with a discussion on cell shape optimization in wireless networks and provides relevant references.
