Title: Juha Heiskala: Innovator in Data Transmission Technologies
Introduction
Juha Heiskala is a prominent inventor based in Helsinki, Finland. He has made significant contributions to the field of telecommunications, particularly in data transmission technologies. With a total of 6 patents to his name, Heiskala's work has had a substantial impact on how data is transmitted in modern communication systems.
Latest Patents
One of Heiskala's latest patents is focused on multipoint data transmission. This patent presents a semi-single frequency network (SFN) concept, where the same data signal is transmitted from multiple base stations to a mobile terminal simultaneously on the same frequency band. The transmitted signals are combined in the radio channel, allowing the mobile terminal to experience them as a single signal propagated through a multipath channel. Each base station also transmits a specific pilot signal, enabling the mobile terminal to perform channel estimation and equalization of the received data signal.
Another notable patent by Heiskala involves a system and method for precoding in a multiple-input multiple-output (MIMO) system. This innovation includes a network entity capable of full-spatial-rate coding data. The entity can provide a full-spatial-rate codebook designed from an underlying partial-spatial-rate codebook. This design allows for the selection of codewords in a manner that exploits correlations, enhancing the efficiency of data transmission.
