Abstract: It is an object of the invention to provide a loop antenna constituted by a single element which can apply a magnetic field to carry out a communication reliably with high precision irrespective of the position and direction of a radio communication medium. The invention provides a loop antenna 1 including a conductor 2, a plurality of bending portions 50 provided on the conductor 2, and a feeding portion for supplying a signal current to the conductor 2, the conductor being turned circumferentially like a loop by setting the feeding portion to be a base point, wherein the conductor 2 forms a three-dimensional space. Consequently, it is possible to generate a magnetic field to all dimensions, thereby carrying out a communication irrespective of the position and direction of a radio communication medium.

Abstract: In a diversity receiver comprising an AGC section for controlling the gain of a tuner, an equalizer equalizes an outputted signal from a fast Fourier transformer. A reliability calculator calculates the reliability value of each of carriers by an equalized pilot signal obtained from the equalizer. A reliability value corrector corrects the reliability value by outputted information from the AGC section. A carrier selecting/combining section performs one of selecting and weighting combining for the carrier in a branch in accordance with the corrected reliability value. When a Viterbi decoder is provided, the Viterbi decoder weights an output from the carrier selecting/combining section with a new reliability value to perform maximum likelihood decoding. It is possible to prevent a reliability value which does not reflect an actually received power from being calculated as a result of increasing a power by an AGC in spatial diversity for every OFDM or FDM demodulated carrier.
