A spatial domain matched filtering method and an array receiver in a radio communication system are provided. A pattern wood is attached to a surface of a plywood structure to form a wood panel. The invention further relates to genetic complements of plants of variety CH273465. The main metal layer has at least one pair of current path regions. This results in a decreased unit-to-unit variation in sensitivity of combustion pressure sensors and ensures the stability of output characteristics of the combustion pressure sensor.
