On pairwise error probability of space-time codes

Proceedings IEEE International Symposium on Information Theory,, 2003
The authors consider a space-time coded system with Q transmit antennas and P receive antennas and assume under the quasi-static Rayleigh fading assumption that the channel is fixed for a duration of M symbol transmissions. Let S be a (Q/spl times/M) space-time code.

A pairwise error probability bound for the exponential- server timing channel

IEEE International Conference on Communications, 2003. ICC '03., 2004
We exhibit upper and lower bounds on the pairwise error probability of the exponential-server timing channel in terms of an appropriately-defined distance between codewords. We show that this distance plays a crucial role in determining the reliability function at low rates. In particular, by lower bounding the minimum distance of good-low rates codes,

Exact pairwise error probability for block fading ofdm systems

IEEE Wireless Communications and Networking Conference, 2006. WCNC 2006., 2006
In this paper, we derive the exact pairwise error probability (PEP) expression for Rayleigh fading OFDM systems. We begin with the quasi-static fading OFDM system, and derive the PEP expression for both the case when the eigenvalues of the channel code are all the same, as well as the more general case when they could be different.

Exact Pairwise Error Probability for Block Fading MIMO OFDM Systems

IEEE Vehicular Technology Conference, 2006
In this paper, we derive the exact pairwise error probability (PEP) expression for MIMO block Rayleigh fading OFDM systems. We begin with the quasi-static fading OFDM system, and derive the PEP expression for MIMO quasi-static fading OFDM system. The exact PEP expression for MIMO block fading OFDM system can then be determined using the general quasi ...

Pairwise error probability evaluation of cooperative mobile femtocells

2013 IEEE Global Communications Conference (GLOBECOM), 2013
Cellular subscribers while travelling in public transportation vehicles, such as streetcars and buses, often experience poor signal reception and low bandwidth when using their cellular devises onboard. Small cell deployment of, for example, femtocells is considered as one of the most promising solutions for cellular operators to enhance coverage and ...

Analysis of the pairwise error probability of noninterleaved codes on the Rayleigh-fading channel

IEEE Transactions on Communications, 1996
The majority of previous analytical studies of signal-space coding techniques (includes trellis and block codes) on the Rayleigh-fading channel have assumed ideal interleaving. The effect of finite interleaving on the performance of different coding schemes has been studied only by simulation In this paper we first derive a maximum likelihood (ML ...

A Simple Moment Based Approximation to Pairwise Error Probability for Memoryless Fading Channels

2005 IEEE 16th International Symposium on Personal, Indoor and Mobile Radio Communications, 2006
This paper provides a simple approximation to pairwise error probability for memoryless fading channels when there is no channel state information at the decoder. The derived approximation is independent of the fading process and depends only on the mean and variance of the fading distribution.

Asymptotic behavior of the pairwise error probability with applications to transmit beamforming and rake receivers

IEEE Transactions on Wireless Communications, 2005
We derive the precise asymptote of the pairwise error probability for high signal-to-noise ratio (SNR) and apply it to obtain new results concerning transmit beamforming and selective Rake receivers. For downlink beamforming (with N transmit antennas and independently identically distributed (i.i.d.) Rayleigh fading) based on quantized feedback from ...

Pairwise error probability of space-time codes in frequency selective Rician channels

IEEE Communications Letters, 2005
In this letter, we investigate the performance of space-time codes in frequency selective correlated Rician channels. An exact expression has been derived for the pairwise error probability (PEP) of space-time trellis codes over frequency selective Rician fading channel, which is in the form of a single finite range integral.

Pairwise Error Probability Analysis for Power Delay Profile Fingerprinting Based Localization

2011 IEEE 73rd Vehicular Technology Conference (VTC Spring), 2011
Although most of the conventional localization algorithms rely on LOS conditions, it is possible to do positioning with Power Delay Profile-Fingerprinting (PDP-F) in multipath and even in NLOS environments. Many algorithms for position fingerprinting have been developed, but analytical investigation in this area is still not matured yet.
