摘要： A receiver (600) uses a scanning technique (100) to minimize scan time. An initial bandwidth setting is selected that covers multiple channel frequencies (106). A signal detection step (108) is performed looking for channel activity. As channel activity is detected, the bandwidth of a baseband filter (628) is narrowed (140, 146). The radio remains programmed to the same channel while the bandwidth is varied. Once the last signal detection with the narrowest possible bandwidth setting has been determined (144, 150, 152) the radio is programmed to that channel. Thus, more than one channel frequency is capable of being scanned without reprogramming the radio to a new channel for each scan.

摘要： A receiver (100) provides dual band features by providing two signal paths (106, 108) off an antenna (102), one for UHF operation (106) and one for VHF operation (108). The two signals paths (106, 108) feed into a single broadband input (124) of a direct conversion receiver (114). The UHF path (106) utilizes UHF front end circuitry (110) while the VHF path (108) is implemented with a loading/isolator circuit (120) and a matching circuit (122). The loading/isolator circuit (120) loads the antenna (102) and isolates UHF signals while the matching circuit (122) provides a match between the loading isolator circuit (120) and the direct conversion recover (114). Selectable matching circuitry (126, 128) and selectable VCO circuitry (132, 134) configures the direct conversion receiver for the UHF or VHF mode of operation.

摘要： A digital radio communication system (200) uses a repeater (216) to relay calls which can not be completed in a direct talk-around mode between two radios. The repeater (216) establishes early synchronization in advance of a pending call by listening to an originator radio (204) attempt to make a direct talk-around call to a target radio (210). Asynchronous digital two-way radio communication systems can benefit from the reduction in voice call connect time.

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.
