In this paper, we propose two new two-dimensional (2-D) IIR and FIR filter architectures for 2-D transfer function using fourfold rotational symmetry. The presented type-I structure with fourfold rotational symmetry has the lowest number of multipliers, and zero latency. Importantly, the proposed type-II IIR filter possesses high speed, local broadcast, and the same number of multipliers and latency...
Four new 2-D filter VLSI architectures without global broadcast are presented. The first is a transposed systolic structure which requires fewer delay elements compared to the original systolic structure. By combining the sub-blocks of the original with the new transposed structure, two additional systolic structures are obtained to realize transfer functions with separable denominators, which require...
In this paper we use a 2D Markov walk model as a mobility model that describes a broad class of mobility patterns such that the location update is designed according to the mobility pattern and traffic parameters adaptively. A location free topology control protocol is used which deals with the topology control at the network layer and at the same time overcomes the hidden terminal problem at the...
An overview of the delta operator based design of 1-D and 2-D filters is presented. The delta operator approach offers better coefficient sensitivity compared to the z-domain approach when the filter is narrowband or when high sampling rates are involved. For 1-D filters, a ladder synthesis procedure is presented. For 2-D filters, an efficient optimization based design procedure utilizing symmetry...
The theory behind the delta operator-based doubly-terminated two-port (pair) is presented for use in filter design and stability testing. The delta operator two-port here is lossless under scaling and the overall network possesses good sensitivity. The continued fraction expansion, developed for extracting the elements of the two-port, can also be used to test the stability of delta-operator-based...
In this paper, we propose two new two-dimensional (2-D) IIR and FIR filter architectures for 2-D transfer function with diagonal symmetry. The presented type-I structure with diagonal symmetry has the lowest number of multipliers, and zero latency without sacrificing the number of the delay elements. Importantly, the proposed type-II IIR filter possesses high speed, local broadcast, and the same number...
A method based on symmetrical decomposition is presented for the design of 2-D IIR filters through optimization. This technique allows a filter with non-symmetric magnitude specification to benefit from the savings in parameters provided by symmetry. The procedure is developed for the delta operator based design to take advantage of its better coefficient sensitivity compared to the z-domain design...
A delta operator based ladder synthesis procedure is presented for the realization of three different types of transfer functions. The procedure overcomes the numerical problem of the conventional z-domain LDI approach when the filter poles are clustered near z=1 and does not require any s-domain polynomial transformation to achieve spectral factorization [4]. Also, the entire operation involves only...
A technique based on symmetrical decomposition is introduced for the design of 2D IIR filters using the delta operator. The use of symmetrical decomposition reduces the computational time in the filter optimization, while the delta operator approach offers better coefficient sensitivity than the traditional z-domain approach when the sampling rate is high or when the filter is narrowband
