LDPC Code based Varying Data Rate Communication Systems with Improved OFDM-MIMO Technology
The rapid evolution of global mobile communication demands high data rate transmission via satellites, which in turn requires spectrally efficient modulation technique and power efficient forward-error correction, schemes. The main objective of any communication system is error free transmission with maximum possible data rate. Noisy communication channels are the major problems in this case. To overcome this problem the authors can use the channel coding along with the suitable modulation scheme. Thus channel coding and modulation have the same objective of producing the appropriate signal waveforms to cope with the noisy channel.
