Abstract :
This paper evaluates the performance of differential modulation applied to the 3GPP UMTS Long Term Evolution downlink. With differential modulation, reference symbols for channel estimation are no longer necessary, thus increasing the potential maximum spectral efficiency. We present two basic modulation schemes and compare their performance to the coherent detection employed in Long Term Evolution downlink transmissions. The focus specifically lies on single input single output transmissions in single user scenarios.
