We experimentally demonstrate that generalised mutual information can be used as a
design rule to select the optimal modulation order and code rate for SNR limited DP-mQAM …

Carrier phase estimation (CPE) is an integral part of the digital signal processing (DSP) of
coherent optical communication systems as it compensates laser phase noise (LPN) …

This thesis covers multidimensional modulation formats for coherent optical communication
systems including spatial division multiplexed systems using multicore fibers. The single …

Reduction of the group delay (GD) spread is crucial for minimizing multi-input multi-output
(MIMO) signal processing complexity in mode-division multiplexing (MDM) systems using …

Network data rates are growing rapidly. The data rates provided to the customers by their
network providers vary from Mbps to Gbps. However, rarely do users get the promised peak …

We study lower bounds on mutual information that are achievable rates for optimal and sub-
optimal hard-decision (HD) and soft-decision (SD) decoding. These rates represent the …
