IMPROVING STBC MIMO - OFDM SYSTEMS WITH PAPR FOR DIFFERENT MODULATION TECHNIQUES
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 4, Issue 6
Abstract
Orthogonal frequency division multiplexing(OFDM) has become a prevalent and widespread technique for the broadcast and transmission of signals over wireless channels .Multiple - Input Multiple – Output Orthogona l Frequency Division Multiplexing (MIMO - OFDM) is a promising Modulation scheme for high Performance Broadband wireless Communication that suffer from major Drawback , which is the high Peak – to - Average Power Ratio(PAPR) of the output signals. In this Pap er a new blind combined Alamouti Space - Time Block - Codes (STBC) approach inspired from Selected Mapping (SLM) Process to solve this PAPR issue for MIMO - OFDM System
