چکیده
In this paper PAPR is reduced at downlink scheme by using PMP pre coding at transmitter section. By using FITRA algorithm with l infinity minimization we can reduce PAR, but practical implementation is complex. To reduce computational complexity of FITRA with hardware implementation we apply l1 minimization to FITRA algorithm with respect to compressed sensing. We prove that this algorithm will reduce PAR efficiently with increased SNR.

PAPR Reduction in MU- MIMO-OFDM Using FITRA with L1 Minimization
In this paper PAPR is reduced at downlink scheme by using PMP pre coding at transmitter section. By using FITRA algorithm with l infinity minimization we can reduce PAR, but practical implementation is complex, to overcome this we use l1 minimization in addition to FITRA algorithm which can reduce computational complexity of FITRA. We compare our results with FITRA.We prove that our method will...
متن کاملMimo-ofdm Downlink Wireless System with Reduced Papr
Orthogonal Frequency Division Multiplexing (OFDM) is a multi -carrier transmission method which is most broadly used in the field of communication. One of the main drawback of this scheme is Peak to Average Power Ratio (PAPR). There are various methods introduce for the reduction of PAPR in OFDM . However these technique have major disadvantage that they reason non linear in-band deformation an...
متن کاملOn Out-of-Band Emissions of Quantized Precoding in Massive MU-MIMO-OFDM
We analyze out-of-band (OOB) emissions in the massive multi-user (MU) multiple-input multiple-output (MIMO) downlink. We focus on systems in which the base station (BS) is equipped with low-resolution digital-to-analog converters (DACs) and orthogonal frequency-division multiplexing (OFDM) is used to communicate to the user equipments (UEs) over frequencyselective channels. We demonstrate that ...
متن کاملSelective 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...
متن کاملA Review on Compressed Sensing based Channel Estimation in OFDM System
MIMO-OFDM technology joins together the focal point of MIMO and OFDM and is generally utilized as a part of high information rate frameworks. Conventional channel estimation of MIMO-OFDM experiences a high cost of huge number of pilots. Channel estimation is discriminating to collector execution in the long term evolution (LTE) system. Reference signs are scattered with information indicators a...
