Abstract: In this paper, we propose a heterogeneous optical access networking scenario, in which communication links between source and destination nodes are heterogeneous, composed of free-space optical, plastic optical fiber (POF), and indoor infrared (IR) links. To deal with bandwidth

Contrary to the common practice of considering the performance of error controlling schemes using the additive white Gaussian noise channel assumption, we consider the performance of the proposed LDPC schemes, taking into account in a

OFDM with quadrature amplitude modulation (QAM) technique can be used for high speed optical applications. Increasing the order of modulation, the bit error rate (BER) increases. Forward Error correction (FEC) coding like LDPC coding is generally used to improve the BER performance. LDPC provides

The ever increasing speed of data transmission especially in optical channels, in magnetic recording devices and in wireless links makes it necessary to look at new receiver structures which are capable of high speed processing at low power consumption. Analog, nonlinear and highly parallel

In this paper, the performance of high speed optical fiber based network is analysed by using dispersion compensating module (DCM). The optimal operating condition of the DCM is obtained by considering dispersion management configurations for the symmetrical system i.e Pre-compensation & Post

Abstract: We propose the reverse concatenated code as a forward error correction (FEC) scheme suitable for beyond 100-Gb/s optical transmission. In this scheme, BCH code is used as inner code and low-density parity-check (LDPC) code as outer code. The BCH decoder is implemented based on maximum a

Mobile Optical Free-Space Communication (MFSO) downlinks from observation platforms in low earth orbit or in the atmosphere will allow nearly undetectable high-speed data links with small and low-power laser communication terminals. Several research institutions and companies are developing MFSO

The replacement of electrical lines by free-space or guided-wave optics in high-performance digital systems is currently of active research interest. Such systems are expected to be operating in full-duplex mode delivering Gbit/s data rate in both directions. The FSO links must be robust and offer

, the simulator implements a fixed-point (FP) iterative decoder that allows control of the precision of the soft information used in the decoder. Such quantization is required to facilitate hardware implementations of the iterative decoder, and the high-speed operations for long-haul optical transmission systems
