Embodiment Construction

[0018] figure 1 A recently proposed arrangement for multiplexing transmit antenna diversity to generate a transmitted data signal is shown in . The useful data signal X is supplied to a diversity channel coder DCOD. The useful data signal X consists of a sequence of data symbols, X=(x 1 , x 2 ,...), for example to represent some data bits. Diversity channel coder according to code rate R C = 1 / n to perform channel coding. This means that n-1 redundant data symbols are added to each data symbol of the useful data signal X. In the example shown, n=3. At the output of the diversity channel coder DCOD a transmit signal is available which consists of n=3 antenna data signals A1(X), A2(X) and A3(X), all having the same data rate. In general, adding redundant information in the diversity channel coder DCOD will increase the data rate of the transmitted signal (consisting of three antenna data signals) by a factor of 3 compared to the data rate of the desired data signal X . ...

Abstract

A method for generating a transmit signal, the signal contains N antenna data signals (A1(X), ..., AN(X)), which can be transmitted through N transmit antennas, wherein the The useful data signal (X) is channel coded. In the signal transmission path between channel coding and transmission via transmit antennas, data rate matching can be performed by a data rate matching stage (RM; RM1, RM2), so that the number of transmit antennas can be pre-defined independently of the code rate (Rc) Sure.

Description

technical field [0001] The present invention relates to a method and device for generating a transmission signal, the transmission signal includes a plurality of antenna data signals, and each antenna data signal must be transmitted through a transmission antenna, as stated in the preamble of claims 1 and 9 Part of the declared form. Background technique [0002] In mobile radio communication systems, the quality of the transmission is influenced by the time variance and frequency selection of the mobile radio channel as well as by time-varying multi-access interference. In general, digital mobile radio systems employ several types of diversity to improve the performance of the system. Known ways of exploiting the frequency diversity of mobile radio channels have CDMA or TDMA components in multiple access. Channel coding and interleaving of data signals to be transmitted usually utilize the time diversity of the channel. A further type of diversity is space diversity. In...
