摘要： A method is provided of discerning a signal of a desired user on a channel having a desired user and a plurality of interfering users, each, upon occasion, transmitting an identifiable, known pilot symbol. The method includes the steps of determining a channel response of the desired user and each of the interfering users and calculating a metric equal to the squared difference between a received signal and a sum of the products of transmitted signals and channel responses for the desired user and each of the plurality of interfering users. The method also includes the step of discerning the signal of the desired user based, at least in part, upon a minimum metric.

摘要： The present invention makes it possible to increase a data rate between a transmitter and receiver using a multiple-input, multiple-output radio frequency channel. A multiple-stream, multiple-antenna receiver measures a composite channel between a multiple-antenna transmitter and a multiple-antenna receiver to produce a composite channel measurement. The receiver selects a plurality of antenna array weight sets for use in the multiple-antenna transmitter in response to the composite channel measurement, where each antenna array weight set is associated with one of multiple data streams. Information describing the plurality of antenna array weight sets for use in the multiple-antenna transmitter are then transmitted.

摘要： Orthogonal transmit diversity is implemented by employing a data splitter (803) to subdivide channel information (801) into at least a first portion of bits (802) and a second portion of bits (804). Each portion is spread with its own Walsh code for eventual transmission to a mobile station via a predetermined carrier frequency. When the number of bits in the first and second portion (802, 804) are small, separate Walsh codes are used to maintain orthogonality. When the number of bits in the first and second portion (802, 804) are relatively large, a time-division multiplex transmission is used to maintain orthogonality. A controller (809) controls the subdivision of the channel information and also an interleaver (308) to further enhance the effects of the diversity transmission. Control information related to the subdivision is transmitted to the mobile station so the channel information can be accurately reconstructed prior to decoding.
摘要翻译：通过采用数据分离器（803）将信道信息（801）细分为比特（802）和比特（804）的第二部分的至少第一部分来实现正交发射分集。每个部分用自己的沃尔什码扩展，以便经由预定的载波频率最终传输到移动台。当第一和第二部分（802,804）中的比特数较少时，使用单独的沃尔什码来维持正交性。当第一和第二部分（802,804）中的位数相对较大时，使用时分复用传输来保持正交性。控制器（809）控制信道信息的细分以及交织器（308），以进一步增强分集传输的影响。将与细分相关的控制信息发送到移动台，使得可以在解码之前准确地重构信道信息。

摘要： In a time division multiple access (TDMA) system (10), a method (50, 60) of recovering a data signal of a transmission burst commences by obtaining the frequency transmission codes for the transmitters to be monitored (52, 62). The data signal is then received in separate transmission bursts from a first transmitter in a first time period (53, 65) and from a second transmitter in a second time period (56, 65). The data signal of one of the received transmission bursts is then selected or a plurality of the data signals are combined (58, 69) to be used by the receiver as the received data signal.

摘要： An individual desiring to operate a pager via voice commands sends a message to a repository of voice recognition codebooks requesting access to a particular codebook. The repository device(s) respond by transmitting the codebook of that individual to at least one pager, which stores the codebook therein. In a second embodiment, each individual operating a pager by voice commands is provided with a codebook module, which contains suitable memory storage having at least that operator's codebook stored therein. By inserting the codebook module (or card) into the pager, that pager becomes at least partially controllable by the voice commands of that operator. The codebook module may be easily removed to permit the communication device to be rapidly reprogrammed by inserting the codebook of another operator.

摘要： In a method for wireless data communication between a base station and a subscriber unit in a wireless communication system, groups of symbols of an input data stream are commutated to produce a plurality of commutated data streams. The plurality of commutated data streams are then transformed to produce a plurality of transformed data streams. Next, each transformed data stream is spread with a selected one of a plurality of spreading codes to produce a plurality of antenna signals. Finally, each of the plurality of antenna signals is transmitted using a selected one of a plurality of spaced apart antennas, wherein the plurality of spaced apart antennas are spaced apart to provide transmit diversity. In one embodiment, the transform is a space-time transform.

摘要： In a cellular communications system having synchronized base stations and unsynchronized base stations, wherein the synchronized base stations are synchronized to system time and have a common pilot PN sequence used for all synchronized pilot channels, a marker sequence is selected. The selected marker sequence is comprised of an M-chip portion of the common pilot PN sequence. Next, a coded portion of an unsynchronized pilot PN sequence is generated wherein the coded portion identifies a selected unsynchronized base station. The marker sequence and the coded portion of the unsynchronized pilot PN sequence are combined to form the unsynchronized pilot PN sequence that is different from the common pilot PN sequence. Thereafter, an unsynchronized pilot channel baseband signal of an unsynchronized base station is spread with the unsynchronized pilot PN sequence to produce the unsynchronized pilot channel.

摘要： The apparatus includes a demodulator (70) responsive to a first received symbol (68) associated with a first transmitted symbol (39). The demodulator has a plurality of outputs (72) and produces a first set of outputs (99). The demodulator (70) is also responsive to a second received symbol (68) associated with a second transmitted symbol (39), and produces a second set of outputs (99). A coherent detector (100) receives some outputs from the first set of outputs (99), producing an estimate of the first transmitted symbol. The coherent detector also receives some outputs from the second set of outputs (99), producing an estimate of the second transmitted symbol. A first energy value (135) and an index (101) are associated with the first estimate, while a second energy value (135) is associated with the second estimate. A averaging circuit (150), which determines an average of the first energy value (135) and the second energy value (135) to produce an average energy value (140), is responsive to the coherent detector (100). A first combiner (130) is responsive to the coherent detector (100), combining the index (101) and the first energy value (135) to produce a weighted index (131). A second combiner (133) is responsive to the averaging circuit (150) and is also responsive to the first combiner (130), combining the weighted index (131) and the average energy value (140) to produce a channel-coded index (141). A deinterleaver (80) is responsive to the second combiner (133), receiving the channel-coded index (141).
