Study on Performance Analysis of HQAM for DCT and DWT Based Compressed Image Transmission over AWGN Channel
Image transmission over a noisy channel is vital in the recent time
because of reliable multimedia transmission. This topic has gained
importance for the purpose of achieving less storage capacity and
required bandwidth during transmitting the image through a noisy
channel. In this paper, prior exertions of compressed image
transmission are illustrated. These exertions are based on two
compressed methods i.e., Discrete Wavelet transform (DWT) and
Discrete Cosine Transform (DCT). Furthermore, overviews of the
polar coding are presented which are used as encoder and decoder for
converting the compressed quantized values to binary code streams.
In addition, the overall advantages of the HQAM over the QAM
modulation scheme are demonstrated in this paper. Finally, by
exploring the preceding efforts, a method is proposed for future work.
In the proposed method the performance of HQAM is analyzed for
DWT and DCT after transmitting the image through the noisy
AWGN channel.
