Method and system for coexistence of radar and communication systems

A communications system comprising:

• a parameter adjustment module that identifies transmission time intervals (TTIs) that are affected by pulses from a pulsed interference source, and changes a transmission adjustment parameter for the TTIs that are affected by pulses,
• wherein the parameter adjustment module identifies a dwell time for which signal strengths of pulses of an oscillating pulsed signal exceed a threshold value, and
• lowers one of a modulation scheme and an FEC rate for TTIs during an opportunity between adjacent dwell times,
• wherein the parameter adjustment module determines an expected signal to interference plus noise ratio (SINR) for the TTIs that are affected by pulses,
• wherein the one of a modulation scheme and an FEC rate is increased based on the expected SINR, and
• wherein the expected SINR is determined based on information of a location and a transmit power of the pulsed interference source.

A non-transitory computer readable medium with computer readable instructions stored thereon which, when executed by a processor, perform the following method:

• identifying a dwell time for which signal strengths of pulses of an oscillating pulsed signal exceed a threshold value;
• identifying transmission time intervals (TTIs) that are affected by pulses from the pulsed interference source;
• increasing one of a modulation scheme and an FEC rate for TTIs during an opportunity between adjacent dwell times;
• and
• determining an expected signal to interference plus noise ratio (SINR) for the TTIs that are affected by pulses,
• wherein the one of a modulation scheme and an FEC rate is increased based on the expected SINR, and
• wherein the expected SINR is determined based on information of a location and a transmit power of the pulsed interference source.
