Fading Channel Classification with Walsh-Hadamard Transform and Convolutional Neural Network
International Conference on Smart Communications and Networking, 2023Fading channel classification is a useful function in the design of wireless communications because the knowledge of the channel state information can help the subsequent steps in the wireless communication processing including the information symbols ...

The Walsh-Hadamard/discrete Hartley transform
International Journal of Electronics, 1987A new fast algorithm is proposed here to compute the discrete Hartley transform (DHT) via the natural-ordered Walsh-Hadamard transform. The processing is carried out on an intraframe basis in (N × N) data blocks, where N is an integer power of 2. The Walsh-Hadamard transform (WHT)W coefficients are computed directly, and then used to obtain the DHT ...

Analysis of Walsh-Hadamard Transformation with CFBMC Communication
2021 International Conference on Artificial Intelligence and Smart Systems (ICAIS), 2021As per tomorrow’s need of fast paced technology, abundant research is required for the advanced communications. The proposed paper discusses about the theoretical observation and comparison of 5G techniques with respect to Walsh-Hadamard Transformation (WHT). It is a precoding algorithm of Circular Filter Bank Multi Carrier (CFBMC). There are the other

Cal-sal Walsh-Hadamard transform
IEEE Transactions on Acoustics, Speech, and Signal Processing, 1978Walsh-Hadamard matrices are rearranged such that the first half of the rows represents cal functions in increasing order of sequency whereas the second half represents sal functions in decreasing order of sequency. The transform based on this rearrangement is called the Cal-Sal Walsh-Hadamard transform or (WHT) cs .

Speech processing with Walsh-Hadamard transforms
IEEE Transactions on Audio and Electroacoustics, 1973High-speed algorithms to compute the discrete Hadamard and Walsh transforms of speech waveforms have been developed. Intelligible speech has been reconstructed from dominant Hadamard or Walsh coefficients on a medium sized computer in a non-real-time mode. Degradation of some phonemes was noted at low bit rates of reconstruction, but the reconstruction

An FPGA based Walsh Hadamard transforms
ISCAS 2001. The 2001 IEEE International Symposium on Circuits and Systems (Cat. No.01CH37196), 2002The Walsh-Hadamard transforms are important in many image processing applications including compression, filtering and code design. This paper presents a novel architecture for the fast Hadamard transform, using distributed arithmetic techniques.
