In broadband communication systems, an analog-to-digital converter (ADC) with few-bit quantization is a promising component in RF front-end to ensure higher sampling rate. To mitigate the nonlinear behavior ADC, stochastic resonance (SR), which improves symbol error rate (SER) presence of noise, has been focused. The SER degrades high signal-to-noise ratio (SNR) region. this paper, we introduce...

This paper reconsiders the Minimum Mean-Squared Error (MMSE) single user adaptive receiver for the asynchronous Direct Sequence – Code Division Multiple Access (DS-CDMA) system. During the training period the classical MMSE receiver adapts the tap weights once every data bit interval. Our aim is to reduce the overhead introduced during the training period. This will be achieved by adapting the ...

In this paper we investigate the achievable rate of LOS MIMO systems that use 1-bit quantization and spatial oversampling at the receiver. We propose that by using additional antennas at the receiver, the loss incurred due to the strong limitation of the quantization can be decreased. Mutual information results show that considerable rate gains can be achieved depending on the number and arrang...

On top of the passively secure extension protocol of [IKNP03] we build a new construction secure against active adversaries. We can replace the invocation of the hash function that is used to check the receiver is well-behaved with the XOR of bit strings. This is possible by applying a cut-and-choose technique on the length of the bit strings that the receiver sends in the reversed OT. We also ...

We examine site selection diversity transmission (SSDT) for 3GPP WCDMA forward link by means of analytical tools. Hard handover (HHO), soft handover (SHO) and SSDT are compared by using the receiver bit error probability as a performance measure taking into account the effect of feedback bit errors as well as the shadow fading. Results show that without fast transmission power control the perfo...

Protocols are developed and analyzed for transmitting a secret bit between a sender and a receiver process using only the information contained in a random deal of hands of specified sizes from a deck of n distinct cards. The sender’s and receiver’s algorithms are known in advance, and all conversation between sender and receiver is public and is heard by all. A correct protocol always succeeds...

A digital dual-rate burst-mode receiver, intended to support 10 and 1 Gb/s coexistence in optical access networks, is proposed and experimentally characterized. The receiver employs a standard DC-coupled photoreceiver followed by a 20 GS/s digitizer and the detection of the packet presence and line-rate is implemented in the digital domain. A polyphase, 2 samples-per-bit digital signal processi...
