The IEEE is working on a MAC standard (802.11 p) for VANET based on 802.11 e. Although
the access function of 802.11 e supports QoS by using different backoff counters and …

A new approach for joint data estimation and channel tracking for multiple-input multiple-
output (MIMO) channels is proposed based on the decision-directed recursive least squares …

In this paper, we present a protocol to collect data within a vehicular ad hoc network
(VANET). In spite of the intrinsic dynamic of such network, our protocol simultaneously offers …

In this paper, a new channel-estimation algorithm based on maximum-likelihood (ML)
algorithm for estimation and tracking of the multiple-input-multiple-output (MIMO) channels is …

In this paper, the performance of decision directed (DD) maximum likelihood (ML) channel
tracking algorithm is analyzed. The ML channel tracking algorithm presents efficient …

The estimation of a time-varying fading channel in multiple-input multiple-output (MIMO)
wireless systems is a difficult task for the receiver. Its performance can be improved if an …

The wireless transmission environment in vehicular ad hoc systems varies from line of sight
with few surroundings to rich Rayleigh fading. An efficient communication system must adapt …

In this paper we consider a multi-input multi-output (MIMO) channel subject to time
variations. These channel variations are due to the presence of a Doppler term which …

In this article, we introduce an algorithm to update the channel estimation in a flat fading
channel. We assume an initial estimate of the channel is available, possibly from a training …

In a vehicle ad hoc network (VANET), vehicles communicate in an ad hoc mode while
moving at high speeds, therefore relative speeds of 200 km/h or more between cars in …
