摘要： A system, wireless device (102) and method reduce the peak-to-average power of a transmitter by creating at least two sampled carrier data streams, running each carrier through a separate delay block, mixing each carrier over in frequency an appropriate amount, resulting in at least two frequency division multiplexed signals, and combining the at least two frequency division multiplexed signals together. The four sampled carrier data streams may each have a bandwidth of 25 kHz. Each separate delay block is less than 20% of its corresponding symbol time. The transmitter may be used to transmit wideband integrated digitally enhanced network (WiDEN) signals.

摘要： An apparatus and method for uplink synchronization without periodic ranging in a communication system includes a first step (700) of detecting embedded pilot signals in data traffic from mobile stations. A next step (702) includes estimating a time error by calculating a pilot signal phase difference across a tone index within the same OFDM symbol. A next step (704) includes estimating a frequency error by calculating a pilot signal phase difference across multiple OFDM symbols within a tone. A next step (706) includes determining if at least one of the estimated time and frequency errors exceed a predetermined threshold. A next step (708) includes sending synchronization information to at least one mobile station for the mobile station to synchronize (710) its transmit signals in response to at least one of the time and frequency error.

摘要： 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 from the plurality of transcoders (4) into a time division multiplexed signal frame (20). Each signal frame (20) includes a plurality of sequential frames (204). Each sequential frame (204) includes a predetermined number of slots (202) 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.

摘要： 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).

摘要： 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.

摘要： A base station and method for selecting a modulation coding scheme (MCS) in an OFDM communication system, includes a first step 500 of estimating the channel response on each antenna based on the uplink feedback. A next step 502 includes calculating transmit weights from the uplink feedback. A next step 504 includes computing a beamformed Carrier-to-Interference plus Noise Ratio based on a broadcast Carrier-to-Interference plus Noise Ratio and the transmit weights and the channel response. A next step 506 includes choosing a best modulation coding scheme for a beamform allocation using the beamformed CINR. A best antenna gain and frequency band can also be chosen using the beamformed CINR.
