Next generation wireless communication systems are essential components in order to increase the capacity of existing digital networks. Channel bandwidth as wide as several gigahertz is generally available at millimeter wave frequencies. However, it is a challenge to design and implement millimeter wave transceivers that can utilize such wideband effectively for the data transmission. In this thesis, the feasibility of high data rate baseband modulators and demodulators (modems) that support various digital modulation formats is investigated. Novel modem structures for OOK, D-QPSK/QPSK, 8-PSK and 16-QAM modulation are presented, and six proof-of-concept modems are designed and verified using these new structures. The work mentioned in this thesis constitutes an efficient portfolio of base- band modem solutions for different wireless communication applications. These modem solutions are optimized for high capacity based on the hardware components that exist today. These solutions may in principle support data rates of up to 100 Gbps, given enough bandwidth and more advanced semiconductor devices.
