This lecture will give you brief journey of wireless communication with the special features.
Explore transmission fundamentals in time and frequency domains, including amplitude, frequency, and phase; bandwidth, spectrum, and Shannon capacity; and analog/digital signals with wireless media and antennas.
Explore how co-channel and adjacent-channel interference impact cellular capacity, and learn how cell planning, power control, and frequency separation mitigate interference.
Learn how capacity in cellular systems is boosted through cell splitting, sectorized antennas, and microcell zones that reduce interference, lower transmit power, and increase channel reuse without constant handoffs.
Explore how multiplexing and multiple access techniques: FDMA, TDMA, CDMA, and SDMA, enhance wireless system capacity with duplex downlink and uplink, narrowband versus wideband, and guard band considerations.
Explore how tdma divides the channel into frames and time slots, allowing multiple users to transmit or receive in nonoverlapping slots with synchronization and guard times.
Learn how code division multiple access uses a spreading signal and a pseudo random code word to multiplex users, increasing capacity and enabling random access and soft capacity.
Mobile phones have changed our lives during the recent four decades and will become an essential and inseparable part of human life. This course will provide how mobile communication is possible from the aspect of communication systems
