碩士 === 國立交通大學 === 電信工程研究所 === 105 === In this thesis, we brief study Multi-carrier Code Division Multiplexing (MC-CDM) modulation in the millimeter wave band, which includes both the uplink and downlink transmission, based on a Massive Antenna MDMA cellular system architecture. In the uplink or downlink system, each user performs code spreading for data multiplexing, rather than for code division to distinguish different user. For the uplink receiver, we use the pilot code to do channel estimation and perform a partial equalization add the antenna diversity combining to detect each user’s data. After data detection in the initial stage, we perform a parallel interference cancellation to reduce the bit error rate further. In the downlink system, we perform a partial pre-equalization before the data transmission. Finally, we compare the MC-CDM simulation results with the simulation results of the OFDM, SC-FDE and CDM-FDE based massive antenna MDMA cellular systems.
