متن کاملQuadrature Amplitude Modulated Codes with Low Peak-to-Mean Envelope Power Ratio for Orthogonal Frequency Division Multiplexing Applications
Orthogonal Frequency Division Multiplexing (OFDM) has been adopted as the modulation technique for many of the next generation wireless broadband multimedia communications systems, for example, Digital Audio Broadcasting (DAB), terrestrial Digital Video Broadcasting (DVB), and the wireless local area network (LAN) standards HIPERLAN/2, and IEEE 802.11a. One problem inherent in plain vanilla OFD...
متن کاملPeak-to-average power ratio reduction in OFDM using cyclically shifted phase sequences
Two approaches for reducing peak-to-average power ratio (PAPR) in orthogonal frequency division multiplexing (OFDM) are proposed that are relied on a set of cyclically shifted phase sequences (CSPS) and implemented using the time domain circular convolution. After multiplying CSPS with the frequency domain data, the signal candidates can be expressed as weighted sum of the circularly shifted OF...
متن کاملMulticarrier radar signals with low peak-to-mean envelope power ratio
A multicarrier phase-coded (MCPC) pulse consists of N sequences of M bits each. The N sequences modulate N carriers that are transmitted simultaneously. The carriers are equally spaced. The carrier separation Df equals the inverse of the bit duration tb forming orthogonal frequency division multiplexing (OFDM). A family of MCPC signals is described, based on modulating all carriers with the sam...
متن کاملAlgebraic space-time codes with full diversity and low peak-to-mean power ratio
A new class of full diversity space-time codes is proposed that leads to a significantly smaller Peak-to-Mean Envelope Power Ratio (PMEPR) compared to the recently invented Diagonal Algebraic SpaceTime (DAST) and Threaded Algebraic Space-Time (TAST) codes. Moreover, the proposed “Low PMEPR Space-Time” (LPST) codes exhibit identical performance and decoding complexity compared to the TAST codes....
