Step-wise implementation of a downlink OFDM system with one Base Station and 2 UEs, Channel Estimation using Max Likelihood, Repetition Coding, and 16QAM modulation. The system uses 20 subcarriers, 5 ...
### Orthogonal frequency division multiplexing (OFDM) is a multi-carrier wideband digital communication system . Used in modern communications systems such a Cellular 4G, Wireless networks , DSL ...
OFDM is a multi-carrier system where data bits are encoded to multiple sub-carriers, while being sent simultaneously. This results in the optimal usage of bandwidth. A set of orthogonal sub-carriers ...
Abstract: An enhanced subcarrier-index modulation (ESIM) based free space optical communication (FSO) system, which is superior to subcarrier-index modulation (SIM) and interleaved subcarrier-index ...
Abstract: The 5G communication is well known for its very high data rates and promising connectivity. This is achieved by employing the OFDM (Orthogonal Frequency Division Multiplexing) technique for ...
