摘要： The invention relates to a method and an arrangement for transmitting a digital signal consisting of symbols, which arrangement comprises a coder (308) for coding complex symbols to channel symbols in blocks having the length of a given K, means (312) for transmitting the channel symbols via several different channels and two or more antennas (314 to 318). The coder (308) is arranged to code the symbols using a code matrix, which can be expressed as a sum of 2K elements, in which each element is a product of a symbol or symbol complex conjugate to be transmitted and a N×N representation matrix of a complexified anti-commutator algebra, extended by a unit element, and in which each matrix is used at most once in the formation of the code matrix. A code matrix is also provided which is formed by matrices of a portion of the symbols placed on the diagonal of the code matrix and by matrices of a second portion of symbols along the anti-diagonal of the code matrix.

摘要： The invention relates to a transmit diversity method for a wireless communication system comprising a transmitting element and at least one receiver, wherein a transmission signal is transmitted from the transmitting element to the at least one receiver in accordance with a weight information determined in response to a feedback information. The feedback information is derived from the response at the at least one receiver to the transmission signal, and is fed back using multiplexed feedback signals. Alternatively, the weight information may be determined at the transmitting element by filtering said feedback information and quantizing the filtered feedback information to a desired quantization constellation. Thus, multiple quantization constellations and combinations thereof and/or constellation specific feedback subchannels can be used for channel probing, such that the total feedback resolution can be enhanced, while maintaining low signaling capacity of the feedback channel.

摘要： The present invention presents a method and apparatus for phase hopping and space-time coding signals for transmission on multiple antennas. The method and apparatus provides expansion of a N×N′ space time block code to a M×M′ space time block code, where M>N, by using phase hopping on the symbols within the N×N′ space time block code to allow transmission of the space time block code on a number of diversity antennas greater than N′. A result of M antenna diversity may be achieved for M transmit antennas.
