A method of allocating resources in a multi-hop wireless sensor network includes (A) when two arbitrary adjacent links among links connecting all nodes have a violation relationship where the two arbitrary adjacent links occupy the same time slot, by a network coordinator node, allocating different time slots to the two arbitrary adjacent links according to a resource allocation request command message from each of nodes configuring the multi-hop wireless sensor network, (B) when two arbitrary links which are not adjacent to each other among the links are within a communication distance, by the network coordinator node, allocating different frequency channels to the two arbitrary links, and (C) when resource allocation for all of the links is completed according to steps (A) and (B), checking whether an end-to-end maximum allowable time required by each of paths established by the links is satisfied.

Provided is a wideband receiver that has a smaller area and consumes less power and can prevent harmonic mixing occurring due to an increase in the number of communications systems using wideband. A wideband receiver according to an aspect of the invention may include: an front-end unit receiving and performing low-pass filtering on a wideband input signal in a continuous-time domain; and a down-conversion unit sampling and holding an output signal of the front-end unit according to a local oscillator signal and performing low-pass filtering on the output signal in a discrete tie domain.
