Multi-Delay Biorthogonal Coded/Balanced TR-UWB Receiver for WPAN Based on Hadamard Matrix
نویسنده
چکیده
Impulse radio ultra wideband (IR-UWB) communication is becoming an important technology for future Wireless Personal Area Networks (WPANs). One of the critical challenges in IR-UWB system design is the inter-pulse interference (IPI). A Transmit-reference (TR) receiver is proposed to completely remove the IPI especially at low input frame energy-tonoise-ratio (Ef/No) values. This receiver is based on the using of a modified version of Hadamard matrix to yield a biorthogonal coded words instead of orthogonal ones. On the other hand, from the complexity view, the proposed TR receiver in this paper has high complexity as compared with the balanced coded orthogonal TR receiver proposed recently but it outperforms it.

Designing a non-ideal delay line (DL) with phase distortion in a transmitted-reference ultra-wideband system (TR-UWB) with an autocorrelation receiver (AcR) is a great technical challenge. Differing from the currently empirical design method of DL, in this paper a semi-analytic approach is proposed through Gaussian approximation of the expression for conditional bit error rate (BER), based on i...
