RNN Encoder 1 is responsible for encoding the past motion of the individual agent. The encoder is implemented with a temporal convolution layer (a.k.a, 1D convolution) that is followed by an RNN with GRU cells [1]. Before putting the past trajectory (Xi) to the temporal convolution layer, we subtract the last state value (present location) from xi,t at all time steps for a translation invarianc...

A common practice for signing with RSA is to first apply a hash function or a redundancy function to the message, add some padding and exponentiate the resulting padded message using the decryption exponent. This is the basis of several existing standards. In this paper we show how to build a secure padding scheme for signing arbitrarily long messages with a secure padding scheme for fixed-size...

In this paper, multi-antenna transceiver for zero-padded orthogonal frequency division multiplexing (OFDM) system is designed at mmWave by integrating full-duplex unmanned aerial vehicle (UAV) into the terrestrial cellular networks. Assuming that there exist no direct communication links between ground base station (GBS) and mobile users due to unexpected blockages from high storied buildings i...

We introduce a fast simple method for computing the real continuous wavelet transform (CWT). The approach achieves O N ( ) complexity per scale and the filter coefficients can be analytically obtained by a simple integration. Our method is to use P wavelets per octave and to approximate them with their oblique projection onto a space defined by a compact scaling function. The wavelet templates ...

This contribution1 details a new OFDM modulator based on the use of a Pseudo Random Postfix (PRP-OFDM) and low complexity equalization architectures. The main advantage of this new modulation scheme is the ability to estimate and track the channel variations blindly using order one statistics of the received signal. This scheme is thus very well suited in presence of large Doppler spreads where...

We show that extremely accurate approximation to the preex sums of a sequence of n integers can be computed deterministically in O(loglog n) time using O(n= loglog n) processors in the Common CRCW PRAM model. This complements randomized approximation methods obtained recently by Goodrich, Ma-tias and Vishkin and improves previous deterministic results obtained by Hagerup and Raman. Furthermore ...

Frequency estimation is a crucial signal processing technique in Phasor Measurement Units (PMU). In this report, we propose a new algorithm for frequency estimation by interpolation of zero-padded discrete Fourier transform (DFT) samples. The bias performance of the proposed estimator is analyzed and an iterative algorithm is further proposed to reduce the bias to an arbitrarily small level. Si...
