Abstract: Wrong handoffs in a cellular radio telephone RF communications system can be minimized or eliminated without increasing locating receiver equipment requirements, field strength measurement time or system response time. Field strength measurements are made at handoff candidate cells and also at cells neighboring (geographically proximate to) those candidate cells. A weighted average of the measured field strength of the candidate cell and the field strength measured in cells neighboring the candidate cell is calculated for each candidate cell (the field strengths measured by neighboring cells may be multiplied by a weighting factor of 0.5). The weighted averages for the candidate cells are compared, and the candidate cell corresponding to the highest average is selected to handle the mobile transceiver call.

Abstract: Digital signals transmitted twice are decoded by a receiver arrangement which determines the value and deviation of each pair of corresponding signals relative to a selected level. A weighting signal indicative of the deviation (either maximum or minimum depending on the selected level) is assigned to each signal. The value of the signal having the greater weight is selected as being correct. Thus, transmitting signals three times for a majority voting is eliminated.

Abstract: A voice-controlled, operator-interacting radio transceiver has a transceiver for transmitting and receiving radio frequency signals under plural potential operating conditions including on/off, transmit/receive, frequency of operation, squelch, volume control, etc. A speech recognition circuit receives audible verbal phrases spoken by a human operator and produces control signals in response to certain predetermined recognized phrases. The operation of the transceiver is controlled in response to the control signals and further coded data signals representative of the respective predetermined operating condition of the transceiver are also produced. Output devices are responsive to the further coded data signal for producing an output signal perceptible to the human operator and confirmatory of the control action then being effected.
