Abstract: The system and method of utilizing frequency waterfilling and implicit coordination to mitigate signal jamming in Link 16 systems. The system and method of utilizing frequency waterfilling for Link 16 includes updates to both software and firmware. The frequency waterfilling approach for Link 16 modifies the process by which data bits are allocated to hops based on an assessment of hops affected by jamming, thus avoiding portions of the spectrum occupied by a jammer.

Abstract: The estimation and mitigation of swept-tone interferers includes receiving a composite signal comprising a signal of interest and a swept-tone interferer over an observation bandwidth or a hop bandwidth in a frequency-hopping system. The estimation of the interfering signal may be based on modeling the interferer as a magnitude periodic signal comprising non-overlapping, contiguous epochs, where each epoch may comprise a common pulse shape and a distinct phase rotation. The modeling may be based over the observation bandwidth, the hop bandwidth, or after combining the signal over all the frequency hop bandwidths. The period of the magnitude-periodic signal may be initially determined, and the common pulse shape and each of the distinct phase rotations may then be estimated. These estimates may be used to reconstruct an estimate of the swept-tone interferer, which may be subtracted from the composite signal to generate an interference-mitigated signal of interest.

Abstract: A frequency hopping receiver circuit has a frequency converter (12) and a hopping control circuit (14) coupled to the frequency converter (12), and configured to control frequency hopping of the received frequency, by controlling changes in frequency shift applied by the frequency converter (12). The frequency change is applied in combination with a temporary reduction in conversion gain of the frequency converter (12) during the change in frequency shift. The frequency converter may contain a mixer (122), a local oscillator circuit (120) and a controllable amplifier (124) coupled between the input of the frequency converter (12) and the mixer (122) or between the mixer (122) and the output of the frequency converter (12), or between the local oscillator circuit (120) and the local oscillator input of the mixer (122). In this case the hopping control circuit (14) has outputs coupled to a gain control input of the controllable amplifier (124) and a frequency control input of the local oscillator circuit (120), to control the reduction in conversion gain and the change in frequency shift respectively.

Abstract: Based on a received signal of a wireless communication system currently used for communication, a communication quality in a case of switching to another wireless communication system for communication is efficiently and precisely estimated. A communication quality estimating part (201) subjects both a known signal received, by use of a first wireless communication system, from a radio part (200) and a reference signal outputted from a reference signal storage part (203) to a conversion processing unique to a second wireless communication system for comparison, thereby artificially estimating the communication quality in a case of using a second wireless communication system for communication under the same wireless transmission path environment.

Abstract: A pilot reception power measuring section measures reception power of a pilot symbol and a data section reception power prediction section predicts reception power of data symbols based on the reception power of the pilot symbol. A power comparison section calculates a difference between this predicted value and the actual reception power of the data symbol, and when the difference is large, a collision position detection section regards the data symbol at the hopping position as colliding with data symbols in other cells. Then, an error correcting decoding section carries out error correcting processing by reducing likelihood of the data symbols detected to be involved in the collision and can thereby improve the error rate characteristic of decoded data.
