Latest Patents

Koya's most recent patents include:

1. **Traffic channel assignment based on traffic density and signal quality** - This innovative radio communication system addresses issues related to traffic density and radio link quality. The method enables a base station to determine the traffic density by evaluating the carrier to interference power ratio (CIR) across multiple channels. When the traffic density is low, it assigns traffic channels that have a higher CIR to mobile stations, whereas, in high-density scenarios, it selects channels with a lower CIR. This dynamic assignment method enhances overall communication efficiency in varying traffic conditions.

2. **Soft decision maximum likelihood decoding method with adaptive metric** - This cutting-edge decoding method corrects burst errors caused by sudden drops in signal amplitude. It employs a multi-valued soft decision likelihood metric, adjusting it based on the instantaneous amplitude of the received signal. By conducting maximum likelihood decoding through these corrected metrics, Koya's invention significantly boosts the error correction capabilities of systems used in mobile radio communication, particularly in environments with severe fading.
