Title: Kjell Östman: Innovator in Radio Communication Technology
Introduction
Kjell Östman is a notable inventor based in Trondheim, Norway. He has made significant contributions to the field of radio communication technology, holding a total of 4 patents. His work focuses on enhancing the efficiency and effectiveness of radio receivers, particularly in the context of Orthogonal Frequency Division Multiplexing (OFDM).
Latest Patents
Östman's latest patents revolve around OFDM channel estimation. One of his innovations involves a radio receiver that tunes a radio channel by generating a periodic signal. This signal is mixed with received radio signals and passed through a channel filter that corresponds to the bandwidth of the tuned channel. The receiver utilizes allocation information to identify a set of subcarriers in the tuned channel for receiving an OFDM data signal. By offsetting the channel filter from the center of the tuned channel, the receiver can effectively pass the OFDM data signal, an in-allocation reference signal, and an out-of-channel reference signal. This allows for accurate channel estimation for a subcarrier within the tuned channel.
Another patent by Östman describes a radio receiver configured to tune to a radio channel by generating a periodic signal and mixing it with radio signals from a transmission system. The channel filter in this design has a passband wider than the channel bandwidth, enabling it to pass the OFDM data signal along with both in-channel and out-of-channel reference signals. The receiver's channel estimation logic uses these reference signals to calculate a channel estimate for an OFDM subcarrier within the tuned channel.
