According to the multiplication theorem, the window function multiplication in the time domain is equivalent to the window function convolution in the frequency domain.
This paper introduces a GFDM modulator and demodulator based on a low-complexity multiplication in the time domain.
Instead, the "power method" [31] can be used for this purpose, whose main operation is matrix-vector multiplication, with the time complexity of O(F 2).
Reducing the frequency of modular multiplications and the time requirements for modular multiplication will help in developing efficient modular exponential algorithms.
The multiplication this time owes far less to logic.
Such multiplication in the time-domain expresses the convolution of the subcarrier filter with the data in the frequency domain for each subsymbol.
Her gift was in her resilience; learning most of her multiplication tables by the time she left, mastering the word spaghetti rather than masketti.
Third, the design decreases the number of multiplications and shortens the time to produce the CWT coefficients.
Performance can be improved in three ways: (i) by reducing the frequency of modular multiplications; (ii) by reducing the time required to evaluate modular multiplication; (iii) by increasing the RSA cores.
Because neural networks rely heavily on matrix multiplication, using GPUs slashes the time it takes to train them from months or weeks to days or even hours, in some cases.
