“…The authors confirmed the superiority of DiPPM in efficiently checking errors, even as performance measured on the basis of the packet error rate can be enhanced using the RS algorithm at the time of error detection [2]. DiPPM errors acquired during transmission can also be eliminated using a maximum likelihood sequence detection (MLSD) error corrector [3]. Additionally, Basman M. Al-Nedawe [3] suggested that the RS code can overcome DiPPM error sources, significantly minimizing the number of errors that occur during transmission.…”

Dicode Pulse Position Modulation (DiPPM) has been presented as a new coding technique with several improvements over earlier PPM formats. Few analyses and experimental results have been published because it is a new coding scheme. To overcome the problem of bandwidth utilization in current PPM formats, DiPPM can be employed. The line rate is twice as fast as the original data rate. In order to increase DiPPM's error performance, two types of Forward Error Correction (FEC) codes, Reed-Solomon (RS) code and low-density parity-check (LDPC) code, are investigated in this article. When RS and LDPC function at their optimal parameters, the results show an improvement in DiPPM system error performance. The error performance of an uncoded DiPPM system was compared to that of a DiPPM-encoded LDPC system and a system utilizing the Reed-Solomon algorithm. Transmission efficiency is measured by the number of photons per pulse and bandwidth widening. When the bandwidth is 1x103 times or more than the initial data rate, DiPPM with LDPC code exceeds uncoded DiPPM and DiPPM with RS, using 1.821 x 103 photons per pulse, with a codeword length of 27 and code rate of 0.75.

“…It was found that DiPPM can be considered as an alternative modulation technique for free space links as it outperforms PCM [15,17]. In order to improve the sensitivity of DiPPM, Reed Solomon (RS) codes or maximum likelihood sequence detection (MLSD) technique can be implemented [18,19].…”

-In this paper a dicode pulse position modulation (DiPPM) technique has been successfully implemented for an indoor visible light communication (VLC) based system using an FPGA and a commercial high power white LED (30 W). A data rate of 13 Mbps has been achieved with a bit error rate (BER) <10 -11 at a free space distance of 1.2 m through a basic transceiver circuit, and 14.5 Mbps with 1.15x10 -6 of BER. Furthermore, a data rate of 13 Mbps has been successfully transmitted over a distance of 1.8 m with BER of 10 -5 . This proves that the application of DiPPM is a viable modulation system over free space communication links.

“…Due to their cost‐effectiveness, optical fibre connections are commonly employed in low‐bandwidth magnetic recording networks. Sibley (2003a) created Dicode pulse position modulation (DiPPM) and Offset as an innovative coding scheme that offers better qualities beyond the PPMs and resolves the bandwidth concern [3]. The DiPPM was created primarily to address the fundamental problem of bandwidth dissipation through the PPM.…”

“…Due to the fact that their output is close to the Shannon limit, LDPC and PPM iterative demodulation systems are useful in deep space algorithms. The Shannon limit is the maximum rate at which error-free data may be sent across a communication channel at a particular noise level when random data transmission failures are occurred within the communication channel [9].…”

Offset pulse position modulation (OPPM) and Dicode pulse position modulation (DiPPM) have been introduced as new attractive modulation techniques, however, they are suffering from erasure, wrong slot, and false alarm errors. in this paper, two types of error correction (EC) codes, Low‐Density Parity Check (LDPC) code and Reed Solomon (RS) code, where paired the OPPM and DiPPM systems to reduce bugs, analyze the best EC parameters, and choose the superlative EC system. In other words, the performance of OPPM engaging LDPC codes and DiPPM employing LDPC codes will be compared against the OPPM engaging RS codes and DiPPM employing RS codes. To systematically carry out this comparison, numbers of photons, transmission efficiency, and the code rate are computed. The evaluation has stated that the data transmission rate at the start has indicated that OPPM with LDPC requires only 1.2 × 103 photons/pulse compared to the necessity of 1.821 × 103 photons/pulse when the DiPPM used LDPC. Accordingly, the transmission efficiency has been increased due to a reduction of number of photons. Also, the coded OPPM with LDPC codes is better than the coded DiPPM with LDPC codes when operating at a code rate that is approximately 0.7.
