|
Wireless communication is observing a fast development in today’s communication era. Planning a good, stable and reliable network can be quite challenging. At the same time, it poses several interesting optimization problems. Here we have analyzed adaptive modulation scheme with their performance in changing channel condition. Different order modulations and different coding schemes, allow sending more bits per symbol, thus gaining higher throughputs and better spectral efficiencies. This paper presents review on various modulation and coding scheme to improve SNR and BER. Here the various modulation types will be implemented in a single Matlab function that can be called with the appropriate coefficients. |
