Narrowband communications has the desirable property of being relatively immune to intersymbol interference but has the undesirable property of being susceptible to flat fading. With conventional Division Multiple Access-Spread Spectrum (CDMA-SS), resistance is achieved by spreading the signal energy over a larger ba. However, the process of providing resistance to deep fade signal is affected by delay spreads to a greater extent, and experiences considerable inter-chip interference. Multi-Carrier CDMA (MC-CDMA) addresses the issue of how to spread the signal bandwidth without increasing the adverse effects of the delay spread. With MC-CDMA, the data symbol is transmitted over many phase-shift keying (BPSK) modulated subcarriers. The scope of this project involves investigating the performance of this modulation / multiple-access technique in an indoor wireless network.
