Ascertaining the importance of the recently proposed spatial modulation, we study its performance in Weibull multipath fading channels. Closed form integral expressions for calculating the symbol error rate of spatial modulation (SM) in independent, not necessarily identical Weibull fading channels are derived. Simulation and the analytical results, considering different transmission scenarios,...

An adaptive minimum symbol error rate (MSER) linear multiuser detector (MUD) is proposed for direct sequence code division multiple access (DS-CDMA) systems employing multilevel pulseamplitude modulation ( -PAM) scheme. Based on a kernel density estimation for approximating the symbol error rate (SER) from training data, a least mean squares (LMS) style stochastic gradient algorithm called the ...

In this paper we describe a trellis representation of variable length coded data which is capable of being used for bit-level or symbol-level maximum a posteriori (MAP) decoding of variable length codes (VLC). A bit-level soft-input/soft-output module is derived and is applied in an iterative decoding structure consisting of an outer variable length code and an inner convolutional code. Due to ...

This paper presents an exact closed-form expression for the symbol error rate of the square and rectangular quadrature amplitude modulation (QAM) constellations, under the assumption that the transmitted and/or received signals are corrupted by the phase noise fluctuation. Phase noise is one of the most important radio frequency (RF) imperfections which usually comes from the local oscillator (...

Adaptive digital filtering has traditionally been developed based on the minimum mean square error (MMSE) criterion and has found ever-increasing applications in communications. This paper presents an alternative adaptive filtering design based on the minimum symbol error rate (MSER) criterion for communication applications. It is shown that the MSER filtering is smarter, as it exploits the non...

Sequence detection is studied for communication channels with intersymbol interference and non-Gaussian noise using a novel adaptive receiver structure. The receiver adapts itself to the noise environment using an algorithm which employs a Gaussian mixture distribution model and the expectation maximization algorithm. Two alternate procedures are studied for sequence detection. These are a proc...

In this article, we concerned with the performance of high rate space time block code (STBC) scheme for Frequency selective fading Environment. Due to large channel delay spread in Frequency selective channel inter symbol interference (ISI) occurred. In high rate STBC, ISI occurs due to loss of „quasi – static‟ assumption and Classical Zero forcing (ZF) receiver produces error floor in Bit erro...

In this paper, a computation of the inputredundancy weight enumerator is presented. This is used to improve the theoretical approximation of the information–bit and –symbol error rate, in terms of the channel bit-error rate, in a block transmission through a discrete memoryless channel. Since a bounded distance reproducing encoder is assumed, the computation of the here-called false positive (a...
