In this paper, we further develop this idea and propose an eﬃcient technique, called two-threshold parallel scaling (TTPS), which can be employed to implement the Gaussian pulse-based Tone Reservation algorithm on digital hardware MIMO-OFDM Wireless Communications with MATLAB® is a key text for graduate students in wireless communications. Professionals and technicians in wireless communication fields, graduate students in signal processing, as well as senior undergraduates majoring in wireless communications will find this book a practical introduction to the MIMO-OFDM techniques. In OFDM links, do we need frequency-domain equalization(FDE), after FFT block of the receiver? In books, it seems that FDE is need if we have a TEQ (channel shortening time domain equalizer) as was studied by Al-Dhahir, etc. With TEQ, there will be phase errors, and I think that FDE can restore the phase.

OFDM transmitter in this example consists of FEC encoder, BPSK modulator and 256 point IFFT. OFDM receiver part consists of FFT, BPSK demodulator and viterbi decoder. This code basically computes the BER of an OFDM system. The ifft size is 64 .16-QAM is the modulation Technique and convolution encoding rate 1/2 is used as the coding scheme.
OFDM systems to avoid the clipping. The results of the FPA algorithm show that the efficiency of the system depends on the throughput, the complexity, and Tone Rate Loss (TRL) of the system. The simulations are first carried out in SIMULINK and MATLAB environments and later on it is synthesized on coarse-grained reconfigurable fabric platform.

Project Files: Ofdm that runs with new matlab, it is a 16 qam one, with comments A major defect of orthogonal frequency division multiplexing (OFDM) systems is the high peak-to-average power ratio (PAPR). In this letter, a novel scheme based on deep leaning, called tone reservation network (TRNet), is proposed for OFDM systems to improve the performance of the tone reservation (TR) technique. More specifically, TRNet reserves a part of tones to generate a peak-canceling MIMO-OFDM is a key technology for next-generation cellular communications (3GPP-LTE, Mobile WiMAX, IMT-Advanced) as well as wireless LAN (IEEE 802.11a, IEEE 802.11n), wireless PAN (MB-OFDM), and broadcasting (DAB, DVB, DMB).
