In this paper we propose a new pipelined architecture for the DLMS algorithm which can be implemented with less than half an amount of calculation compared to the conventional architectures. Although the proposed architecture enables us to reduce the required calculation, it can achieve good convergence characteristics, a short latency and high throughput characteristics simultaneously.
A super-resolution method based on the discrete cosine transform (DCT) is proposed for a signal with some frequency damage under a type 1 linear-phase (LP) FIR filter as a damage model. The proposed method can be carried out with real value operation and is applicable to any DCT in 4 kinds of DCTs. In addtion, two magnification schemes based on the proposed method to improve the conventional scheme...
This paper proposes a method for increasing the throughput of recursive least squares (RLS) adaptive filters when only a few processing elements (PEs) are available. Throughput can be traded against the rate of convergence by varying a parameter. Because the conventional methods for improving the throughput of an RLS filter require the use of more or faster PEs, the proposed technique will expand...
