A Purely Symbol-Based Precoded and LDPC-Coded Iterative-Detection Assisted Sphere-Packing Modulated Space-Time Coding Scheme [PDF]
, 2006 In this contribution, we propose a purely symbol-based LDPC-coded scheme based on a Space-Time Block Coding (STBC) signal construction method that combines orthogonal design with sphere packing, referred to here as (STBCSP).

Near-Capacity Iteratively Decoded Space-Time Block Coding
, 2008 Iteratively decoded near-capacity Space-Time Block Coding (STBC) schemes are designed. Recursive unity-rate codes and IRregular Convolutional Codes (IRCCs) are employed for assisting the conventional non-recursive STBC schemes in achieving decoding ...

The VHL tumor suppressor at the crossroad of protein folding, aggregation, and cancer
Molecular Oncology, EarlyView.Mutations, environmental stress, and chaperone dysfunction can destabilize pVHL, promoting its conversion from the native folded state into amyloid‐like assemblies. This transition may contribute to protein storage, cell dormancy, survival, and drug resistance.

ICA based blind detection scheme in space-time block coding communications
Tongxin xuebao, 2007 Space-time block coding（STBC） schemes are capable of improving system performance by using transmit diversity strategy and specific coding schemes.Nevertheless,they need precise channel state information（CSI） at the receiver end in order to achieve good ...

Sphere-Packing Modulated Space-Time Coding Using Non-Binary LDPC-Coded Iterative-Detection
, 2008 A recently proposed Space-Time Block Coding (STBC) signal construction method that combines orthogonal design with sphere packing, referred to here as (STBC-SP), has shown useful performance improvements over Alamouti’s conventional orthogonal design. In

Autocorrelation based channel estimation method for space-time block coding system
Tongxin xuebao, 2007 An autocorrelation based method was proposed to estimate the channel of the space-time block coding（STBC） system.It is shown that when the inputted symbol vector is spatially white,the autocorrelation of the received signal has specific structure due to ...

Molecular Oncology, EarlyView.Incomplete microwave ablation (iMWA) of liver cancer triggers a biphasic progression in residual tumors. At Day 3, the microenvironment is characterized by acute inflammatory responses and extracellular matrix (ECM) remodeling. By Day 14, a profound shift occurs toward oncogenic signal transduction and immunosuppression, marked by macrophage ...

Distributed convolutional-coded differential space-time block coding for cooperative communications
, 2010 A low complexity distributed coding scheme is proposed for communications over Rayleigh fading channels. Convolutional Coding (CC) assisted Differential Phase-Shift Keying (DPSK) modulation is employed at the source node for conveying the source signals ...
