Performance Analysis of BER Using Efficient Coding and Interleaving Techniques in MIMO-OFDM System
Error free transmission is the main aim of wireless communication. However nowadays with the increase in multimedia services there is a demand for ever increasing data rates. To reduce the bit error rate forward error correction methods (FEC) methods are now employed. In this paper we compare the BER performance of 16-QAM and 64-QAM modulation techniques with and without interleaving process. A...
متن کاملBER Analysis of Modulation Techniques Based OFDM System
Efficient utilization of the spectrum is the key challenges is multiplexing technology, and have OFDM is a transmission technique which ensures efficient utilization of the spectrum by allowing overlap of the spectrum by allowing overlap of carriers. It has various advantages like high spectral density, its robustness to channel fading, its ability to overcome several radio impairment factor su...
