Before attempting to understand how 4G and 5G networks are made up, it is important to have a comprehensive understanding of GSM. GSM is an acronym that stands
1. Introduction Energy efficiency is one of the main goals for the next mobile network generation. As we mentioned in previous posts, theeNodeBs are the elements in the
In this study, we explore the 16QAM scheme for its higher data rate capabilities in comparison with QPSK and BPSK, suitable for the most bandwidth demanding wireless systems
If you want to do a full study of this technique, we would definitely suggest to download and “play” with our Matlab implementation: https://uk.mathworks.com/matlabcentral/fileexchange/55995-cyclic-prefix-in-16qam-system-with-single-path-rayleigh The Cyclic Prefix technique commonly
DSSS is one of the methods widely used in code division multiplexing access (CDMA) systems such as IS-95 standard, or the more recent ones: UMTS and EVDO, all
Nowadays is difficult to imagine our lives without mobile communications. We are replacing the use of desktop computers by mobile phones and tablets that perform the main applications
In previous posts we saw the properties of DSSS signals and the rake receiver implementation for a 16QAM system. We have upload the following files to Mathworks: http://www.mathworks.com/matlabcentral/fileexchange/55810-direct-sequence-spread-spectrum-dsss-for-bpsk-qpsk-and-16qam-modulations BPSK
The typical channels that model the multipath behaviour of the wireless link are either a combination of the exponential channel model, or the Rayleigh channel model, together with AWGN
