Web12.4 Polyphase Filters Polyphase is a way of doing sampling-rate conversion that leads to very efficient implementations. But more than that, it leads to very general viewpoints that are useful in building filter banks. Before we delve into the math we can see a lot just by looking at the structure of the filtering…. WebThe polyphase and bicubic algorithms allow scaling to be performed in such a way as to preserve sharp edges, but without losing the smooth interpolation effect on graduated areas. For down scaling, a long polyphase filter can reduce aliasing effects. The bicubic and polyphase algorithms use different mathematics to derive their filter coefficients.

Webpolyphase decomposition on the input, the polyphase decimation ﬁlter is written: Y(z) = NX−1 k=0 R(X,k)(z)E(H,k)(z) • Complexity Analysis: We compute as many ﬁlter taps, but per N samples. Hence, complexity is reduced by factor N. • Multistage Decimation • If decimation by a large factor is required, it’s often better to break it ... WebPolyphase decomposition has been traditionally used to implement parallel structures in DSP. In this paper, two versions of polyphase decimation filters intended for high speed data stream are proposed. The polyphase decimators were derived from Hogenauer’s structure [5] which has been proven to be very efficient. 2. CIC DECIMATION FILTERS

WebWe consider the design of polyphase waveforms for ground moving target detection with airborne multiple-input-multiple-output (MIMO) radar. Due to the constant-modulus and finite-alphabet constraint on the waveforms, the associated design problem is non-convex and in general NP-hard.
