Latest Patents

Norio Hama's latest patents include a "High performance signal structure with multiple modulation formats" and "Fast response automatic gain control." The first patent describes a mapping memory designed for use with a transmitter. This technology allows for the mapping of two signal segments within a packet, ensuring that each segment maintains the same average power level while utilizing different modulation formats. For instance, one segment may employ Binary Phase Shift Keying (BPSK), while the other utilizes Quadrature Amplitude Modulation (QAM) with multiple amplitude levels.

The second patent, "Fast response automatic gain control," outlines a two-step automatic-gain-control (AGC) loop intended for receivers. This system amplifies received signals and generates a received-signal-strength-indicator (RSSI) signal that reflects the power level of the incoming signal. The AGC amplifier adjusts its gain based on the stored AGC signal, which is updated through a series of error determinations and normalization processes.
