In LTE orthogonal space frequency block codes (OSTBC) are used that allow simple receiver structures ⇒Symbol by symbol detection rather than vector detection. The main attractive feature of STBC is the quaternionic structure (see Appendix for more discussions on quaternions) of the spatio-temporal channel matrix. detection algorithms. In the Bayesian setting, the change-point is modeled as a geometrically distributed random variable. For this case, the average detection delay (ADD) and the probability of false alarm (PFA) are used as performance metrics. We propose a novel algorithm, namely the parallel-sum algorithm, for the purpose of change detection.

Abstract: The paper presents an efficient parallel carrier synchronization algorithm suitable for high speed demodulator system and easy to implement on FPGA platform. The parallel algorithm combines the phase frequency detector (PFD) algorithm of the fast capture and the phase detector (PD) algorithm of the stable by: 1. A low-complexity multiple-input multiple-output (MIMO) subspace detection algorithm is proposed. It is based on decomposing a MIMO channel into multiple subsets of decoupled streams that can be detected separately. The new scheme employs triangular decomposition followed by elementary matrix operations to transform the channel into a generalized elementary matrix whose structure Cited by:

In [18, 19], the M-algorithm to maximum likelihood (MML) detector with prioritized tree-search structure was presented.

A fully-parallel structure is developed, and through systematic reformulations of the algorithm, the computational requirements are reduced considerably. In addition, the problems associated with a large dynamic range such as overflow (or underflow) are (practically) removed.

This Letter proposes a new symbol detection scheme for an uplink wide-banded cyclic prefixed filter bank multiple access system. The feature of the proposed scheme is that it eliminates the analysis filter bank processing that is commonly employed in the existing schemes. By leveraging a particular interleaving structure, the large matrix inversion operation is decomposed into parallel Cited by: 1.

Corresponding to these three Gaussian approximations, three low-complexity iterative parallel soft interference cancellation [5, 11] algorithms, namely, joint Gaussian detector (JGD), grouped joint Gaussian detector (GJGD), and graph-based iterative Gaussian detector (GIGD), will be described by utilizing factor graphs [12, 13] as a general Cited by: We propose a symbol-by-symbol (SBS) detector for Gaussian minimum shift keying (GMSK) signals in body area networks (BAN).

Our detector exploits the orthogonality between adjacent GMSK-modulated symbols. By dividing the received signals into inphase-/quadrature-channels and odd-/even-streams, the strongest inter-symbol interference (ISI) from the adjacent symbols is removed.

Abstract: Time selectivity of multipath channels introduces significant inter-carrier interference (ICI) in OFDM systems demanding high levels of mobility and capacity.
