In this paper, we derive a closed-form expression for the combiner of a multiple-input-multiple-output (MIMO) receiver equipped with a minimum-mean-square-error (MMSE) estimator. We propose using variable-bit-resolution analog-todigital converters (ADC) across radio frequency (RF) paths. The combiner designed is a function of the quantization errors across each RF path. Using very low bit resol...

Cryptographic devices are vulnerable to the nowadays well known side channel leakage analysis. Secret data can be revealed by power analysis attacks such as Simple Power Analysis (SPA), Differential Power Analysis (DPA) and Correlation Power Analysis (CPA). First, we give an overview of DPA in mono-bit and multi-bit cases. Next, the existing multi-bit DPA methods are generalized into the propos...

TeraHertz (THz) wireless communication constitutes a promising technique of satisfying the ever-increasing appetite for high-rate services. However, ultra-wide bandwidth THz communications requires high-speed, high-resolution analog-to-digital converters, which are hard to implement due their high complexity and power consumption. In this paper, deep learning-assisted receiver is designed, reli...

This paper presents recent developments on a dynamic model for a mono-tube cavity receiver for direct steam generation with large scale parabolic dishes. Simulations of the model show that it is possible to assume a homogeneous distribution of heat flux along the receiver pipe without loosing accuracy in the calculation of receiver outlet temperature. The model in its current state produces an ...

In this paper, a turbo receiver for MIMO-CDMA systems employing parity bit selected and permutation spreading is proposed. In such systems, spreading codes used by transmit antennas are dependent on the transmitted data. In the proposed system, convolutional coding is used as an outer code, while the parity bit selected scheme is used as the inner code. Detection and decoding are performed iter...

Abstruct-In the present state of the art, coherent optical receivers most often operate in the heterodyne mode. Here a photodiode-,amplifier combination having bandwidth greater than twice the bit rate ( B ) is needed: indeed bandwidths considerably greater than 2B are preferably employed to ease design of the bandpass filter needed for noise limitation, and to avoid demodulator penalties in so...

This lecture covers our final subtopic within the “exact and approximate recovery” part of the course. The problem we study concerns error-correcting codes, which solve the problem of encoding information to be robust to errors (i.e., bit flips). We consider only binary codes, so the objects of study are n-bit vectors. Recall that a code is simply a subset of {0, 1}; elements of this subset are...

as functional integration has increased in hand-held consumer devices features such as global positioning system (gps) receivers have been embedded in increasingly more devices in recent years. for example, the train positioning system based on gps provides an integrated positioning solution which can be used in many rail applications without a cost intensive infrastructure. the network built i...
