Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and method for transmitting/receiving a multiplexed signal which exhibits no voice delay and voice quality degradation.
SOLUTION: An iDEN is provided with a base radio unit (104) which is interconnected to a plurality of transcoders (4) located in a central office (2). The base radio unit (104) multiplexes voice packets from the plurality of transcoders (4) on a time division multiple signal frame (20) in the time division manner. Each signal frame (20) contains a plurality of consecutive frames (204). Each consecutive frame (204) contains a predetermined number of slots (202) on the basis of channel interleave. Each slot (202) contains a slot descriptor block (2024) and a plurality of sub-slots (2026, 2028). The slot descriptor block (2024) alternately contains overhead information for the plurality of sub-slots (2026, 2028).

Abstract: A time division multiple access communication system is provided having multiple sub-channels according to known quadrature amplitude modulation techniques. Each sub-channel has a pre-determined time duration and is divided by a pre-determined number of symbol position time divisions. The symbol positions carry color codes and ACP codes in addition to sync, pilot and data symbols. Pilot symbols in the second half of the slot are replaced with dual purpose color code and ACP symbols. The dual purpose symbols are either modulated with a lower order modulation than data symbols or are repeated values of dedicated symbols located earlier in the same slot, or both. Slot throughput is attained with a minimal bit error rate penalty.

Abstract: An Integrated Digital Enhanced Network system (1) includes a base radio (104) interconnected to a plurality of transcoders (4) located at central offices (2). The base radio (104) time division multiplexes voice packets fr om the plurality of transcoders (4) into a time division multiplexed signal fra me (20). Each signal frame (20) includes a plurality of sequential frames (204) . Each sequential frame (204) includes a predetermined number of slots (20 2) based upon a channel interleave. Each of the slots (202) includes a slot descriptor block (2024), and a plurality of subslots (e.g., 2026, 2028). The slot descriptor block (2024) alternatively contains overhead information for the plurality of subslots (e.g., 2026, 2028). The subscriber device (30) demultiplexes each sequential frame (204) and receives a specific slot (202) and a specific subslot of the specific slot based upon an assigned slot offset. The subscriber device (30) executes a handover process (600) for determining a timing for jumping to a time division signal frame (21) generated by a new base radio.

Abstract: A time division multiple access communication system is provided having multiple sub-channels according to known quadrature amplitude modulation techniques. Each sub-channel has a pre-determined time duration and is divided by a pre-determined number of symbol position time divisions. The symbol positions carry sync, pilot and data symbols. Color code information is incorporated into the sync and pilot symbols. The QAM constellation value of the sync symbol is mapped to a color code value. In addition, the sync symbol carries a color code extension which enlarges the color code space.

Abstract: Disclosed is a method and communication device for suppressing interference. The method comprises performing, with a turbo decoder (314), at least one turbo decoding attempt (1106) on a received signal (1104). The turbo decoding attempt generates at least one whole word code bit therefrom (1108). The whole word code bit (1108) corresponds to a group of bits comprising a transmitted symbol. The method determines if the whole word code bit (1108) has a confidence level exceeding a given threshold (1110). If the whole word code bit (1108) does have a confidence level exceeding the given threshold, the whole code word bit is selected for use in data symbol recovery (1114).

Abstract: In the present sampling technique of a transmitted data stream, a data stream is divided (318, 504) into a predefined number of sample streams to provide a plurality of sample streams, and for at least two of these sample streams, a metric value is assessed (324, 514, 516) and compared (328, 518) to provide a selected sample stream that is likely to resemble transmitted tones as represented by the data stream. The selected sample stream is then accordingly provided (330, 520) for output.
