In this paper, we propose a constrained convex sets-based method for designing ultra-wideband (UWB) pulse. The UWB pulses designed using earlier proposed methods either do not fit well in UWB spectral mask or require extra processing circuitry for pulses to fit in the UWB spectral mask. The proposed constraint sets-based method is flexible and optimum for the UWB mask. The pulse designed by the proposed method is Federal Communication Commission compliant and has an autocorrelation function similar to the Gaussian pulse. The bit error rate performance of time hopping binary phase shift keying using the proposed method and some of the existing methods such as Norman and Lee pulses and sixth derivative Gaussian pulse is analyzed in additive white Gaussian noise and Saleh-Valenzuela channels. Pulse designed using the proposed method outperforms existing pulse design, and the same is verified through simulations. The proposed algorithm is flexible and can also be used to mitigate narrow band interference, multiband UWB pulse generation and any other Federal Communication Commission (or other regulatory body) compliant spectrum mask by modifying the parameter of the proposed constraint set(s). INTRODUCTIONThe impulse radio ultra-wideband (UWB) technology is being adopted in IEEE 802.15.4 task group for unlicensed short-range high-data rate wireless transmission and can be used for other upcoming applications such as millimeter wave communications. 1 This unlicensed communication technology requires low power and low cost and, hence, can be used in low power wireless devices such as sensor networks, high-data rate wireless local area network, personal area network communication, various imaging and radar systems, and internet-of-things. 2-6 However, the UWB communication pulse design is a crucial and challenging task because pulse should be maximally flat in frequency, and narrow in time domain. Therefore, sinusoidal pulses are not suitable for UWB communications. Generally, convex optimization-based techniques have been used for the UWB pulse design. 7,8 Various UWB pulses are proposed in literature such as Gaussian, Hermite, and Prolate Spheroidal and using combination of orthogonal polynomials in. 4,9 Pulses used in UWB communications should satisfy the US Federal Communication Commission (FCC) spectral mask. 4 The UWB pulse should have minimum narrow band interference; therefore, its compatibility with FCC mask is desirable. The FCC mask compatible pulse can be designed with the help of projection onto the convex sets (POCS). The required convex sets are formulated based on a given a priori information about the UWB pulse. The proposed method in this paper for pulse designing is generic and flexible and, hence, can be easily applied FCC and other than FCC UWB standards, and also can be used for both single-and multiple-user environments. A vast literature on using various methods for UWB pulse design is available; hence, in this section, we review some of the commonly used UWB pulse designs. In Parr et al, 10 the U...

A New Sparse Signal-Matched Measurement Matrix for Compressive Sensing in UWB Communication

2016

Ultra wideband (UWB) technology is suitable for high data rate short range wireless communication, localization, and imaging techniques. However, UWB systems require high sampling rate and precise synchronization. In order to reduce the sampling rate, have precise synchronization, and for low power requirement, UWB systems are implemented using compressive or sub-Nyquist rate measured samples by exploiting the sparsity of the UWB signal. Compressive sensing (CS)-based UWB systems are being designed in two ways: 1) signal demodulation or detection is performed in the CS domain without full signal recovery at the front-end. Thus, demodulation or detection works on compressive measurements. However, system performance deteriorates in the CS domain as compared with full Nyquist rate sampling and 2) after, Nyquist rate signal is recovered using efficient algorithms at the front-end, the signal demodulation or detection is performed using the conventional receiver. Thus, one requires an efficient CS/sampling of signal measurement at the front-end for better system performance for both the cases stated earlier. In this paper, we propose a deterministic (partial) UWB waveform-matched measurement matrix. The proposed measurement matrix has a circulant structure and is sparse in nature. The proposed matrix is easy to implement in hardware and is operationally time efficient as needed in a practical system. The bit error rate performance of the corresponding UWB system and the operational time complexity with the proposed measurement matrix are better as compared with the existing measurement matrices in the CS domain for both the above receiver designs. The efficacy of the proposed measurement matrix is verified through extensive simulations in both the additive white Gaussian noise and multipath communication environments. In addition, we have also compared other desirable properties of the proposed measurement matrix with the existing measurement matrices.
