نویسندگان
چکیده
In this paper, the performance of block coding scheme based on complementary sequences, which allows coding gain and reduction of peak to average power ratio(PAPR) of multicarrier signals, is evaluated over frequency selective Rayleigh fading channel, employing the efficient soft decision decoding method. Above all, 8-carrier QDPSK and 8DPSK systems exhibit good performance in terms of bit error rate improvement, feasibility of practically optimal decoding with a moderate coding rate, and the resultant PAPR at most 3dB.

Selective Tone Reservation method for PAPR reduction in SFBC-OFDM systems
The high Peak to Average Power Ratio (PAPR) of Orthogonal Frequency Division Multiplexing (OFDM) and MIMO-OFDM systems reduces the system efficiency. In this paper, an extension of Tone Reservation (TR) method is introduced for PAPR reduction in Space Frequency Block Coded OFDM (SFBC-OFDM) systems. The proposed algorithm is based on a time domain kernel which is added to the signal of the anten...

Inti.odzietion: Multicarrier modulation techniques have been proposed for digital TV broadcasting and high speed wireless networks over multipath channels [l]. A main drawback of multicarrier modulation is that the peak transmitted power may be up to N times the average, where N is the number of carriers. Linear amplifiers that can withstand the peak power are less efficient. Hard limiting of t...
