COMMUNICATION APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18222070 titled 'COMMUNICATION APPARATUS
Simplified Explanation
- The patent application describes a communication apparatus with multiple receiving antennas that receive interference signals and desired signals transmitted by a transmitting apparatus. - The apparatus includes an interference suppressor that generates weights for each receiving antenna to combine the reception signals and perform interference suppression. - The interference suppressor applies reverse sequence multiplication processing to vary interference forms in the reception signals. - Different combinations of reception signals are used to generate different weights for interference suppression. - The interference suppressor selects weights that strengthen the desired signals when performing interference suppression.
Original Abstract Submitted
A receiver that is a communication apparatus includes a plurality of receiving antennas that receives, as reception signals, interference signals and desired signals transmitted by a transmitting apparatus that performs sequence multiplication processing at the time of transmission, and an interference suppressor that generates, for each of the receiving antennas, a weight used when combining the reception signals received by the respective receiving antennas, and performs inter-antenna combining that is combining of the reception signals, using the weights, to perform interference suppression on the reception signals. The interference suppressor performs reverse sequence multiplication processing on the reception signals to vary interference forms in the reception signals, generates the weights differently for different combinations of the reception signals on which to perform the interference suppression, and performs the interference suppression using, from among the generated weights, the weights by which the desired signals strengthen each other.
