Advanced modulation formats can enable >40 Gb/s data rates in waveguide-based optical interconnects without the need for high-specification optoelectronic components. Record 56Gb/s PAM-4 data transmission is demonstrated over a 1 m-long multimode polymer waveguide.
We report record error-free data transmission of 40Gb/s over a 1m-long multimode polymer spiral waveguide. The waveguide imposes no significant transmission impairments in the link despite its highly-multimoded nature and long length, demonstrating its potential in high-speed board-level optical interconnections.
In this paper, we consider the use of the Golden Code within two-way transmission over a wireless relay network in the fixed and selected relay cases. Such two-way transmission potentially improves the rate performance over one-way schemes. A four time slot amplify-and-forward (AF) protocol is exploited. Two policies are considered for relay selection, one based on a maximum-minimum strategy and a...
We propose the use of simple full inter-relay self interference cancellation (FSIC) at the relay nodes within a four relay network. The four single antenna relay nodes are arranged as two spatially well separated groups of two relays with offset transmission scheduling. This approach can achieve the full available distributed diversity order and its end-to-end transmission rate can asymptotically...
We propose the use of simple full interference cancellation (FIC) and orthogonal frequency-division multiplexing (OFDM) within a two-hop asynchronous cooperative four relay network. This approach can achieve the full available diversity and asymptotically full rate. The four relay nodes are arranged as two groups of two relay nodes with offset transmission scheduling. Therefore, the source can serially...
We proposed RF direct-detection vector signal generation using optical I/Q up-conversion. The Gram-Schmidt orthogonalization procedure is employed to compensate I/Q imbalance. After transmission over 100-km SMF, penalties of 5-Gb/s QPSK signals can be ignored.
The performance of band limited M-ary PSK communication systems is impacted by amplifier nonlinearities. It is critical to precisely model high-power amplifiers (HPAs) to ascertain the bit error rate (BER) performance of M-ary PSK communication systems, which are band limited. State-of-the-art simulation techniques can be employed to exactly ascertain intersymbol interference (ISI) and its degradation...
