Two-tier cellular networks consist of a group of contiguous microcells overlaid by a macrocell. This design provides an enhanced use of the networks’ resources for both high and low speed users because of the availability of additional channels. However, this causes an increase in the number of handoffs between cells due to having smaller cell sizes in the(More)
A new current-mode multifunction filter using minimum number of passive elements is proposed. The proposed filter has single-input and four high-impedance outputs. It uses four passive elements (two capacitors and two resistors) and four dual output second generation current conveyors. Each output provides a different filter response, namely, low-pass,(More)
Two-tier cellular networks provide an enhanced use of the networks' resources for both high and low speed users. However, they cause an increase in the number of handoffs between cells due to having smaller cell sizes in the microcell tier. An effective approach used to prevent the dropping of ongoing calls in a network is delaying these calls in a queue(More)
A new voltage-mode triple-input single-output multifunction filter using only two current conveyors is presented. The proposed filter which possesses three inputs and single-output can generate all biquadratic filtering functions at the output terminal by selecting different input signal combinations. The validity of the proposed filter is verified through(More)
