OFDM Receiver Design Based on Adaptive Modulation and Channel Estimation for Underwater Acoustic Communication
Abstract: Submerged or under water acoustic communication (UWAC) is an intriguing area in communication research where we can expect to get a high information rate, a high throughput and a low latency which frequently is an exceptionally difficult assignment. In this work, we outline an OFDM receiver system that is reasonable for submerged acoustic communication in view of adaptive modulation and Kalman filter based channel estimation. We have concentrated on the …

Non-healing Ulcer Treatment with Unani Formulation Zaroor-e-Qawi: A Case Series
Abstract: Non-healing ulcers (Qurooh-e-Aseeerat-ul-Indamaal) are those ulcers which do not heal by conservative treatment within six weeks. In Indian community its prevalence reported in year 2004 was 4.8 per1000 populations. About 1% of total western population suffers from it. This estimate is likely to increase many folds because of the increasing population of elderly people and the people with uncontrolled diabetes mellitus, arterial and venous diseases. It badly affects the patient’s …
