摘要： A reference device determines its distance from a communication device by first using a training process to determine a calibrated time delay for the communication device when the communication device is at a known distance from the reference device, wherein the calibrated time delay comprises a steady state internal processing delay for the communication device. Subsequently, when the reference device is at an unknown distance from the communication device, the reference device determines the unknown distance using the previously determined calibrated time delay.

摘要： Methods of enabling late entry into an on-going spread spectrum call are described. A late join frame replaces, and has the same size as, a traffic frame. A late join slot in the late join frame contains sufficient information in preamble and sync subframes to permit a target to join the call. The traffic slots in the late join frame replicate data such that call quality of the call is substantially unaffected if one of the remaining traffic frames is not received. The preamble and sync subframes frequencies may be the same as, or different from, preamble and sync frames frequencies during a call establishment phase of the call. If different, the preamble and sync subframes frequencies are selected from one or more frequencies. Use of the preamble and sync subframes frequencies is compensated for when selecting the traffic slot frequencies to obtain uniform utilization of the spectrum.

摘要： A frequency generation unit (FGU) 100 includes a plurality of selectable voltage controlled oscillators (110) whose output frequencies are chosen in relationship with a predetermined intermediate frequency (IF) and frequency divider value (M) to provide multi-band frequency generation capability in a single communication device. A programmable reference divider (104), phase detector (174) and programmable charge pump (106) take an incoming reference frequency (120) and generate a charge pump output (124) to optimize the in-band phase noise in the FGU 100. A fixed loop filter (108) filters the charge pump output (124) to generate a control voltage (126) for the selectable VCOs (110). The desired frequency band is selected and enabled using control logic (128).
