Comparison between dicode PPM and offset PPM enhancement with different error correction codes

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

متن کاملOptical wireless communications utilizing a dicode PPM PIN-BJT receiver
Original results are presented for an optical wireless system employing dicode pulse position modulation (DiPPM) and a PINBJT receiver. When operating at 0.85 m and a bit rate of 10 Mb/s, a sensitivity of 51 dBm (Pe 10 ) is achieved, which represents a 10.3-dB improvement, as compared to an equivalent PCM system. The work also demonstrates that DiPPM achieves comparable sensitivities to those o...

Original results are presented for an optical wireless system employing dicode pulse position modulation (DiPPM) and a PIN-BJT receiver. When operating at 0.85 m λ μ = and a bit rate of 10 Mb/s a sensitivity of –51 dBm (Pe=10) is achieved and this represents a 10.3 dB over an equivalent PCM system. The work demonstrates that DiPPM achieves comparable sensitivities as that for the digital PPM fo...
