Performance analysis of hybrid Fi-Wi network employing OCDMA based NG-PON

Abstract

Fiber-Wireless (Fi-Wi) networks play a crucial role in broadband wireless communication. A hybrid Fi-Wi architecture integrating Optical Code Division Multiple Access (OCDMA) based Next-Generation Passive Optical Network (NGPON) with Long Term Evolution (LTE) is proposed that can provide a higher capacity to the mobile end users, thereby achieving scalability and mobility. Maximal length sequence (M-sequence) codes of code length 31 used can support six users. A simulation study is carried out for the proposed integrated architecture considering multiple users and multiple services, and the performance is analyzed in terms of the received Bit Error Rate (BER) and Error Vector Magnitude (EVM) values. A high capacity of 160 Gbps and a spectral efficiency of 2–4 bps/Hz are achieved for the multi-user and multi-service links with six users.

Design of long‐reach symmetric 1.6 Tbps bidirectional NG‐PON2 using 2D spectral/spatial SWZCC code

“…Also, to address the shortcoming of one-dimensional (1D) OCDMA system such as MAI and phase induced intensity noise (PIIN), two-dimensional (2D) spectral/spatial single weight zero-cross correlation (SWZCC) are most preferable codes to enhance the system capacity. 1,3 Recently, in Rajasekaran et al 4 hybrid fiber wireless (Fi-Wi) based NG-PON using maximal length sequence OCDMA code at 160 Gbps data rate has been proposed. High-speed Gigabit PON (GPON) using ID OCDMA code over 20 km has been presented in Memon et al 5 In Meftah et al, 6 a hybrid OCDMA-PON using 2D cyclic shift over 33.2 km at 1.5 Gbps transmission rate has been proposed.…”
