rfid_model
- A system simulation environment in Matlab/Simulink of RFID is constructed in this paper. Special attention is emphasized on the analog/RF circuit.Negative effects are concerned in the system model,such as phase noise of the local oscillator,TX-RX
noise
- This matlab file is used to generate noise signal which is added to the transmitted signal in an AWGN channel. Based on the SNR value the power of the noise is determined.
Channel
- AWGN channel. Uses a file called BPSK (containing BPSK voltage levels) and adds gaussian noise to it. The noise is generated by box muller equation. Note: BPSK file was generated from BPSK modulator source: BPSK.c
extended_reciever
- Bit Error Rate analysis of an Extended Receiver for Rectangular PAM. The performance of a digital communication system in the presence of additive white Gaussian noise (AWGN) can be assessed by the measurement of the bit error rate (BER). The Si
TURBOCODEAPPTOIMAGETRANSMISSION
- Simulations over AWGN and Rayleigh channels, at various signal-to-noise ratios, verify the excellent performance of this novel APEL-turbo scheme. Performance comparisons were carried out between turbo coded APEL, JPEG, and BMP image files. To provi
