Pass band data transmission

Pass band data transmission. In digital pass band data transmission the transmitted data bits are modulated onto a carrier There are three basic signaling schemes used in pass band these are Amplitude shift keying (ASK), the data bits modulates the amplitude of the carrier.

Bit Error Rate Performance Evaluation of Different Digital Modulation and Coding Techniques with Varying Channels

This paper focuses mainly on Bit Error Rate BER , Signal to Noise Ratio and different Rayleigh channels. We have designed four Rayleigh channels. This paper describes the comparative analysis of different digital modulation techniques like BPSK, QPSK, 8PSK, 16PSK and 16QAM for four Rayleigh channels which are designed. We also compare the convolution coding with different code rates i.e. 1 2, 1 3 and 2 3 code rate for various channels. Here we use MATLAB2009b software.
