“…Only the Planck-taper window, which uses mathematical expressions to organise signals at equal intervals, can achieve this effectuality while preserving linearity and positioning the signal by preventing it from exceeding the limit. As a result, the signal on the receiver side, which the DAC transformed into analogue, has gained linearity and is now on the transmission channel, where the addition of noise can do so with poor quality [16]. The technique is briefly described below, and Figure 1 shows the overall block diagram of the OFDM approach using the suggested way.…”

The issue of transferring signals in a non-intrusive and efficient manner is highly intriguing. Consequently, the utilisation of the Orthogonal Frequency Division Multiplexing (OFDM) transmission technology is employed due to its enhanced resilience against multipath fading and its ability to achieve better efficiency compared to alternative wireless communication methods. Although the PAPR issue offers certain benefits, it poses undesirable consequences for OFDM, leading to a significant decrease in data transmission rate. Consequently, the mitigation of peak-to-average power ratio (PAPR) issues leads to an improvement in the quality of service. The reduction of PAPR can be achieved by the implementation of clipping and windowing techniques. These approaches arrange the signal into discrete levels of similar magnitude and apply clipping to minimise the bit error rate (BER), resulting in a drop in PAPR. The proposed approach is implemented using the MATLAB software.

“…One of the Multicarrier transport technique called OFDM, it is used in high-speed communication systems. A single data stream is divided into many narrowband channels at various frequencies using the OFDM method of digital signal modulation to minimise interference and crosstalk [7]. The idea for OFDM technology initially emerged in the 1960s and 1970s.…”

In wireless communications, Orthogonal Frequency Division Multiplexing (OFDM) is a method of modulating multicarrier signals to transmit high speed data. OFDM systems use multiple subcarriers to transmit the modulated symbols. There is a high peak to average power ratio (PAPR) in OFDM. PAPR can be reduced by using various methods. Different PAPR minimization techniques, like clipping, selective mapping (SLM) and partial transmit sequence (PTS) are presented in this project. This paper also focuses on Bit Error Rate (BER) and Signal to Noise Ratio (SNR) relative performance. A significant reduction in the PAPR and computational complexity can be seen from the results. The purpose of this study is to compare the results of an analysis recommended for PAPR reduction methods.

“…The transmission of information is achieved by assigning each subcarrier to represent a single bit of data, resulting in a total of N bits. This is determined by the presence or absence of the subcarrier in the output spectrum [17]. The selection of the frequency for each subcarrier is done in order to create a collection of orthogonal signals.…”

The widespread use of mobile platforms has resulted in significant challenges related to power constraints and the Quality of Service(QoS) provided by Orthogonal Frequency Division Multiplexing (OFDM) systems. The examination of Bit Error Rate (BER) and Signal-to-Noise Ratio (SNR) is of significant importance in comprehending and enhancing the design of OFDM systems. The utilization of wireless technology in everyday life has experienced a gradual and consistent growth. OFDM is a prevalent technique for multicarrier transmission, which effectively utilizes parallel data streams. OFDM is considered an effective technique for achieving high-speed digital transmission over channels that exhibit time-varying characteristics. OFDM has several advantages compared to single carrier modulation. These include enhanced resistance to impulsive interference, increased spectral density, improved resilience to channel fading, greater tolerance to multipath effects, and reduced computational complexity. Nevertheless, OFDM has some notable challenges that hinder its practical use in telecommunications networks. Several examples of these are packet loss, bit loss, peak-to-average power ratio (PAPR), BER, and SNR. This research aims to investigate the BER and SNR performance of OFDM in the presence of Rician Fading Channel. The study also explores the impact of different modulation techniques on the performance of OFDM.
