Her screens were monstrosities, double polyphase lattices that looked about as spacetight as so many sieves.

The IF signal bandwidth on the output of the polyphase low-pass ﬁlter is in range 1-11 MHz.
The multifrequency Siberian Radioheliograph
Since 2009, the survey has been recording data using the Jeff Mock spectrometers, which are polyphase ﬁlterbanks that provide better radio frequency interference rejection as well as increased bandwidth compared to the earlier WAPP survey data.
Four Highly Dispersed Millisecond Pulsars Discovered in the Arecibo PALFA Galactic Plane Survey
Waveforms that fall in the ﬁrst category are for example polyphase sequences2, since they give rise to signals with low peak-to-average power ratio3 (PAPR). A low PAPR is desirable in the digital-to-analog conversion of signals, since signals with large PAPR would require expensive power ampliﬁers.
Accurate detection of moving targets via random sensor arrays and Kerdock codes
Polyphase sequences also have the advantage that they can be very convientiently implemented in hardware via simple look-up tables.
Accurate detection of moving targets via random sensor arrays and Kerdock codes
Quite a number of polyphase sequences, such as Alltop sequences or Kerdock codes, fall in this category.
Accurate detection of moving targets via random sensor arrays and Kerdock codes
Since Kerdock codes are polyphase sequences, they have excellent PAPR and they are easy to implement in hardware via a simple look-up table.
Accurate detection of moving targets via random sensor arrays and Kerdock codes
Since there is a one-to-one correspondence between Zq -valued and polyphase codewords, in the remainder of this letter, we shall drop the distinction between them.
Simple Maximum-Likelihood Decoding of Generalized First-order Reed-Muller Codes
From the discussion in Section II we know that a polyphase codeword x ∈ RMq (1, m) may be expressed as x = (w|w ξ i ), where w ∈ RMq (1, m− 1) and i ∈ Zq .
Simple Maximum-Likelihood Decoding of Generalized First-order Reed-Muller Codes
If {ψ (ν ) j k } is a tight frame and M is its polyphase matrix with polynomial entries, then, due to Suslin’s theorem and Lemma 10, there exist (r + 1) × (r + 1) polyν,k=0 , eN = {eµν k }r nomial matrixes N = {µν k }r ν,k=0 extending M such that N eN T = Ir+1 .
Multivariate Wavelet Frames
Now we will show that starting with arbitrary trigonometric polynomials satisfying (31), (32), it is possible to improve them such that the improved polynomials are polyphase representatives of a reﬁnable mask generating a tight frame with V M n property.

Even greater channel densities may be achieved using polyphase ﬁlter banks or similar techniques.

This is so called polyphase representation of trigonometric polynomial t.
On construction of multivariate symmetric MRA-based wavelets
If we change the set of digits, the polyphase components of trigonometric polynomial t will also change.

Thus, we need to reformulate symmetry conditions for the mask in terms of its polyphase components.

Let us reformulate axial symmetry conditions (43) for mask m0 in terms of its polyphase components.
