Collision Model for Bit Error Rate analysis of Time Hopping Impulse Radio in Multipath Nakagami-m Channels
— In presence of multiple access interference, the performance of impulse radio system is affected by collisions with other users. In this paper we evaluate the bit error probabi...

Parallel Repetition of Computationally Sound Protocols Revisited
Abstract. Parallel repetition is well known to reduce the error probability at an exponential rate for single- and multi-prover interactive proofs. Bellare, Impagliazzo and Naor (1...

On the Impact of I/Q Imbalance in Multi-Carrier Systems for Different Channel Scenarios
— I/Q imbalance has been identified as one of the most serious concerns in the practical implementation of the direct conversion receiver architecture. Facing the performance-de...

Biorthogonal matrix dirty paper coding for information hiding in still images
In this paper, a new method of dirty paper code design is investigated, namely the biorthogonal matrix. The error probability is analysed for the code design. Since the code has t...

A realistic performance analysis for practical channel-aware scheduling
It is well-known that opportunistic transmission schemes are sumcapacity optimal, in the Shannon sense, for symmetric cellular networks with single-antenna transceivers. However, ...

Quantum lower bound for the collision problem
The collision problem is to decide whether a function X : {1, . . . , n} {1, . . . , n} is one-to-one or two-to-one, given that one of these is the case. We show a lower bound of...
