Abstract This paper investigates codebook-based precoding for spatial modulation (SM) and generalized spatial modulation (GSM) systems.Codebook-based precoding allows the system to dispense with full channel state information at the transmitter (CSIT).This considerably reduces the feedback overhead.Phase-only codebooks with systematic structure are
A driving technical concern for the automobile industry is their assurance that developed windshield products meet Federal safety standards.Besides conducting innumerable glass breakage experiments, product developers also have the option of utilizing numerical approaches that can provide further insight into glass impact breakage, fracture, and fr
ABSTRACT Wound infections with methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE) are particularly difficult to treat and present a great challenge to clinicians.Nanoemulsions (NE) are novel oil-in-water emulsions formulated from soybean oil, water, solvent, and surfactants such as benzalkonium chloride (B
Classification of different deadly diseases using machine learning algorithms helps in making the health care system more robust.This, not only reduces the human errors during diagnosis of disease due to inexperience but also helps the Metal Keychain physician for taking an emergency action earlier to biopsy.As the genomic data undergoes through th
Phrenic nerve palsy is a common complication of interscalene block (ISB), which is usually found incidentally and is typically asymptomatic when affecting Bucket hats only the unilateral side.However, underlying lung diseases like sleep apnea can manifest as respiratory failure.We present a case of a 73-year-old woman with a history of sleep apnea
