متن کاملAnalysis Of Orthogonal Frequency Division Multiplexing ( Ofdm ) Scheme For Mobile Radio Channel
Orthogonal Frequency Division Multiplexing (OFDM) is a transmission technique which ensures efficient utilization of the spectrum by allowing overlap of carriers. OFDM is a combination of modulation and multiplexing that is used in the transmission of information and data. Compared with the other wireless transmission techniques like Frequency Division Multiple Access (FDMA), Code Division Mult...
متن کاملBlock-spreading codes for impulse radio multiple access through ISI channels
Transmitting digital information using ultra-short pulses, Impulse Radio (IR) has received increasing interest for Multiple Access (MA). Analog IRMA utilizes pulse-position modulation (PPM) and random time-hopping codes to mitigate inter-symbol interference (ISI) and suppress multiuser interference (MUI) statistically. We develop an alldigital IRMA scheme that relies on block-spreading and judi...
متن کاملMultistage block-spreading for impulse radio multiple access through ISI channels
Transmitting digital information using ultra-short pulses, impulse radio (IR) has received increasing interest for multiple access (MA). When IRMA systems have to operate in dense multipath environments, the multiple user interference (MUI) and intersymbol interference (ISI) induced, adversely affect system capacity and performance. Analog IRMA utilizes pulse position modulation (PPM) and rando...
