WebThree different techniques, noncoherent combining, coherent combining with sign recovery and differentially coherent combining, are analyzed for the joint acquisition of data and … Webthe Non-coherent detection does not show a significant reduction in the values of BER as SNR increases. Also, the numerical values reveal that, the mean value of BER for coherent detection and non-coherent detection receptions are 0.6135or 61.35%, and 0.7401 or 74.01% respectively. This actually shows BER value difference of about 13%.
