Many error detection and correction codes have been studied. There are vast classes of such codes; some of them are hamming codes, turbo codes, BCH codes and LDPC codes. But among these codes LDPC codes achieve better performance and lower decoding complexity. LDPC codes were originally discovered by Robert G. Gallager. But after the rediscovery of LDPC codes by Mackay and Neal in 1995 interest on LDPC codes increases because of its bit error performance approaches asymptotically the Shannon limit. An LDPC code is a special class of linear block codes whose parity-check matrix H has low density of ones i.e. sparse. Due to this sparsity in LDPC codes there is low complexity decoding and its implementation is also simple. Also LDPC codes provides large degree of parallelism that can be exploited in the decoder and in LDPC codes information block length are long enough. In addition LDPC codes provides wide range of trade-offs betw...
Two Port Compact Wideband Dielectric Resonator MIMO Antenna for WLAN/WiMAX Applications

Unfortunately millions of people sustain from various Heart diseases, and Heart attack is the primary cause of Death in the world and increasing of heart diseases mainly due to the negligence of their health because they don't have time for themselves and forget about their health protection due to a massive workload. Accurate and exact prediction of the heart disease mainly depends on Electrocardiogram (ECG) data and patient clinical data. In this paper, we are going to make an IOT Based Heart Disease Prediction and Monitoring system using Arduino and raspberry pi 3. We utilize an AD8232 Heart rate sensor module to interface to the Arduino board, and Arduino board serially communicates to the raspberry pi board.NEO6MV2 GPS module interfacing to PL2303 USB to TTL for performing a function of USB to UART in between the raspberry pi and GPS.

Four Port Multiple Input Multiple Output DRA for WLAN/WiMAX Applications
2021 IEEE MTT-S International Microwave and RF Conference (IMARC)

Four cylindrical dielectric resonator antennas are placed on the upper part of the substrate and are fed with an aid of a rectangular aperture such that any two adjacent radiating antennas are orthogonal to each other. The antenna works in the frequency range of 5.03 to 5.92GHz. At the resonant frequency, the reduced mutual coupling is depicted to be better than -30dB. The diversity performance of the stated radiator is also found within optimal limits.
