I have been making research and preparing thesis regarding with OFDM and its applications for my work . To understand OFDM more and more, I want to simulate it with Matlab. If it is possible, could you supply me a matlab code or codes which are able to simulate OFDM (for example matlab program which may simulate BER performance predicti

DGPA-Based Tone Reservation for PAPR Reduction in OFDM Systems. December 2018; DOI: 10.1109/CompComm.2018.8780927. Conference: 2018 IEEE 4th International Conference on Computer and Communications

In this work, we consider ourselves with the performance of the tone reservation in … 2009-10-17 This section of MATLAB source code covers OFDMA transmitter and OFDMA receiver MATLAB code. Following download link provides the generic OFDMA matlab transmitter code. Unlike OFDM where in data from mapper is mapped on to all the used sucarriers of the entire FFT, In OFDMA subcarriers of the entire FFT is divided into subchannels and few of the subchannels are allocated to one mobile … Apply OFDM modulation assigning null subcarriers. Initialize input parameters and generate random data.

In literature, the results of work based on channel capacity investigating this optimization problem [8] confirm the results of the study based on the OFDM Tone Reservation (TR) is a technique proposed to combat the high Peak-to-Average Power Ratio (PAPR) problem of Orthogonal Frequency Division Multiplexing (OFDM) signals. However conventional TR suffers from high computational cost due to the difficulties in finding an effective cancellation signal in the time domain by using only a few tones in the frequency domain.

tone location, and scaled so that the power of the peak tone should be reduced to the desired target clipping level. But this operation affect the whole value of OFDM symbol in frequency domain, i.e., not only C but also X is changed. So another impulse-like function is designed, which only has the value in the tone locations {, , }ii1 LL.

It is called also, multi tone modulation scheme, can somebody plz share the matlab code of BER Vs SNR curve for OFDM under rayleigh fading using 4, 16 QAM on mail id mesamriti@yahoo.co.in. 对于如何降低OFDM中的PAPR，接下来主要研究TR(Tone Reservation)这种方法。预留子载波法最初由Tellado提出，其主要思想是在所有的子载波中，只选择一部分用于传送数据信息，而在其余子载波上插入预定的冗余数据，通过在频域设计冗余数据，经过IFFT变换后，在时域抵消峰值来抑制PAPR，原理如下所示： The following Matlab project contains the source code and Matlab examples used for tone reservation as a papr reduction technique. if we have 16 subcarriers let us dedicate r1,r2,r3 and r4 as PRC or peak reduction carriers and transmit on x1:x12 so when x1:x12 summation creates a peak, a combination from r1,r2,r3 and r4 creates an anti peak but not the exact anti peak or the output would be a 7.1.2 Distribution of OFDM Signal 216 7.1.3 PAPR and Oversampling 218 7.1.4 Clipping and SQNR 222 7.2 PAPR Reduction Techniques 224 7.2.1 Clipping and Filtering 224 7.2.2 PAPR Reduction Code 231 7.2.3 Selective Mapping 233 7.2.4 Partial Transmit Sequence 234 7.2.5 Tone Reservation 238 7.2.6 Tone Injection 239 7.2.7 DFT Spreading 241 The source code and files included in this project are listed in the project files section, please make sure whether the listed source code meet your needs there.
