Uplink Capacity of Cellular System Using Frequency Domain Adaptive Antenna Array

Space Division Multiple Access (SDMA) using Adaptive Antenna Array (AAA) allows multiple users to simultaneously access using the same bandwidth and hence is spectrum efficient. Single-Carrier (SC) transmission has been widely adopted by uplink communication due to its lower Peak-to-Average-Power-Ratio (PAPR) than Multi-Carrier (MC) transmission. However, broadband SC channel is frequency-selective and the Inter-Symbol Interference (ISI) is produced in addition to the multiuser interference. Frequency Domain AAA (FDAAA) is a combination of AAA and Frequency-Domain Equalization (FDE). In this paper, the uplink capacity is investigated for the cellular system with FDAAA.
