Diversity is a technique in wireless communication, where the information is sent through multiple paths. Hence, even though one of the communication link is in deep fade, the receiver can still recover the information that has been transmitted.The most striking feature is that it does not ...
OFDM is a technique used to combat Inter Symbol Interference (ISI) in wireless communication systems. OFDM offers high reliable data rate over frequency selective channels. But the drawback is high Peak to Average Power Ratio (PAPR) whic... R Sarankumar,K Sumathi,GS Sravanthi,... - 《Iop ...
12 A hybrid pulse interval modulation--code-division multiple- access (PIM-CDMA) is proposed for optical wireless communication systems. It offers higher transmission rate compared with the hybrid pulse position modulation (PPM)-- CDMA due to its non-fixed frame structure. Strict optical orthogonal...
