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 ...

This repos contains the implementation of IEEE 802.11 (i.e. Wifi) OFDM-based transceiver system. This is stored in 2 separate parts, i.e. transmitter (TX) and receiver (RX). MY_SOURCES contains hdl ...

Abstract: Cyclic prefix (CP) is used in OFDM/OFDMA systems for data transmission over multipath channels at a dear price of spectral efficiency degradation. This work aims to design a CP-free ...

Abstract: DFT-spread-OFDMA (DFT-S-OFDMA) technique has been adopted as the uplink access scheme in emerging cellular systems such as the 3GPP long term evolution (3GPP-LTE), in order to reduce the ...

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 ...
