Peak-to-Average Power Ratio Analysis for Golden Coded MIMO Systems
The combination of the orthogonal frequency-division multiplexing (OFDM) technique and the multiple-input multiple-output (MIMO) architecture has emerged as a promising candidate for future wireless communications. The Space-time block coding (STBC) technique permits to fully take advantage of MIMO-OFDM systems and to effectively improve the channel capacity and the spatial diversity. The Golde...
متن کاملTrellis Coded Mapping for Peak to Average Power Reduction in Sfbc Mimo Ofdm Systems
Space frequency block code orthogonal frequency division multiplexing (SFBC-OFDM) systems has inherit drawbacks of high peak-to average power ratio (PAPR) signals, and constellation shaping with trellis is a promising approach for reducing both peak power and bit error rate of SFBC-OFDM signals. In practice, reliability will improve in SFBC-OFDM by employing coded modulation. In this work, it h...
متن کاملCompanding Technique for Reducing Peak-to-Average Power Ratio in OFDM Linear Coded Systems
Orthogonal Frequency division multiplexing (OFDM) is a very attractive technique in wireless communications which provides robustness to channel fading and immunity to impulse interference. Despite of its advantages, one of the major drawbacks of OFDM system is very high peak-to-average power ratio (PAPR). Among the various PAPR reduction techniques, companding appears attractive for its simpli...
متن کاملPeak to Average Power Ratio Reduction for Mimo-ofdm Systems with Decomposed Selected Mapping
A major drawback of multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) systems is its high peak-to-average power ratio (PAPR). A decomposed selected mapping algorithm is proposed to overcome this problem. The candidate OFDM frames transmitted on antennas are decomposed to be real and imaginary part, thereby, a sufficiently large number of alternative transmit ...
متن کاملReducing the peak to average power ratio in OFDM systems
High peak to average power ratio of the transmit signal is a major drawback of OFDM systems. After defining the PAPR and analyzing its statistical properties, some of the most representative PAPRreduction techniques available in the literature are reviewed in detail. Several methods have been proposed to reduce the peak power of OFDM signals. In this paper the effectiveness of some recently pro...
