Abstract

In this paper, we present an iterative algorithm which jointly estimates the PA characteristics and the channel impulse response for communication systems. The proposed approach is motivated by the fact that the nonlinearly amplified communication signal carries more bandwidth, referred to as spectral regrowth, and therefore allows better probing of the channel. In contrast to existing conventional schemes, where the expansion of the bandwidth is treated as a distortion, we propose to exploit the spectral regrowth to enhance channel identification accuracy. Numerical results show that an improved performance is achieved by using the proposed approach over the ones that ignore the outband energy of the received signal.
