Title
Channel Estimation For Ofdm Fft/Dwt In Multi-Carrier Modulation Used In Wireless Telemedicine
Abstract
This paper proposes an OFDM system to be used in the ECG Patient Monitoring System (ECG-PMS) for wireless telemedicine applications. The system needs a level of transmitted power at the patient site, and achieves a high BER performance at the hospital base station. This achieved by implementing a wavelet-based OFDM system that uses channel estimation based on the improved Data-Aided technique called Forward Error Correction coding Decoded Pseudo Pilot (FDPP). The performance of wavelet-based OFDM systems and Discrete Fourier Transform (DFT)-based OFDM system using FDPP-based as well as Hard Decision Pseudo Pilot channel estimation techniques are compared. The system model was studied using MATLAB software in which the average BER was addressed for randomized data, and the difference between the transmitted and received signals provide a measure of the ECG signal quality. A better BER performance achieved by using OFDM-DWT(haar) system than OFDM_FFT system, thus our system requirements achieved successfully
