In this paper, we study an innovative multiple access scheme that exploits the intrinsic properties of the wireless envi- ronment to improve the multiuser environment, so-called Channel Division Multiple Access (ChDMA) focusing on spectral efficiency analysis and system performance. In particular, we show that Simultaneous multiuser accessing to a common destination is made possible by considering the channel impulse response (CIR) of each user as a signature. We begin by the assumption of the channel state information available at the receiver. Then, we analyze the perform- ance of the ChDMA integration in a random environment over UWB high data rate channel. Next, we discuss the de- sign of MMSE and optimal receiver structure for such a system. Additionally, we show an asymptotic analysis behavior taking into account the channel eigenvalues distribution with the associated spectral efficiency.
