Latest Patents

Colin Brown's latest innovations include:

1. **Iterative Non-Coherent CPM Decoder**: This invention presents a method for non-coherent decoding of an encoded Continuous Phase Modulation (CPM) signal received by a wireless receiver. The method features an iterative decoding process that uses a non-coherent CPM detector to identify dominant sequences of CPM symbols, thus maximizing path metric for effective decoding. The adaptation of soft inner bits and the use of extrinsic information provided by an outer decoder further refine the decoding accuracy, crucial for systems involving frequency-hopping RF carriers.

2. **Frequency Hopping Communication System**: This adaptive system utilizes frequency hopping spread-spectrum (FHSS) technology to improve transmission efficiency and robustness against jamming in wireless communication. By transmitting a wide-band signal over multiple parallel subbands, the invention allows for better bandwidth utilization while maintaining a high data rate. This innovative approach demonstrates significant error rate performance improvement over traditional single-subband systems without compromising transmission power.
