Pilot Based Synchronized Detection

Abstract

In this chapter, we compare the achievable rate with i.i.d. zero-mean proper Gaussian inputs as it has been considered in the two previous chapters to the achievable rate while using synchronized detection in combination with a solely pilot based channel estimation, as it is used in many typical receivers. In the context of synchronized detection, the receiver tasks are separated into two units. In the so-called inner receiver the unknown channel fading weights are estimated and then used for coherent detection/decoding1 in the outer receiver.
