    Abstract: The embodiments of the present invention relate to a method in a transmitting unit; a method in a receiving unit; a transmitting unit and a receiving unit, in a wireless communication network employing Time Division Multiple Access, TDMA, for transmitting and, receiving and demodulating data, respectively, the data being transmitted in a signal comprising a burst, wherein bursts relating to NMS number of mobile stations are multiplexed into a single time slot. The transmission comprises grouping a block of N b number of user code bits, representing the data to be transmitted, into NDS/NMS groups of user code bits. Mapping the groups of user code bits to data symbols such that one group is represented by one data symbol, thereby obtaining a block of data symbols, wherein each data symbol is drawn from one or more pre-defined complex-valued symbol constellation(s). The transmission further comprises repeating the block of data symbols, such that the burst to be transmitted comprises NMS number of equal blocks of data symbols, rotating the NMS number of blocks of data symbols according to a mobile-station-specific rotation, and transmitting the rotated blocks of data symbols in a burst in the time slot.

    Abstract: Non-linear distortions, called glitches, occur in radio receivers when automatic gain control (AGC) is employed for regulating the dynamic range of the received signal. It is proposed to determine (S1) the occurrence of a glitch caused by operation of the AGC mechanism, and estimate (S2) a representation of how energy of a signal transient associated with the glitch is transferred by digital filter(s) in the receiver. The radio signal is then detected (S3) at least partly based on the estimated representation. In this way, the adverse effects of the glitch can be mitigated and detection of the desired signal can be significantly improved. This also means that the link performance will be significantly improved.

    Abstract: In a radio transmission scheme reusing slots such as by using Orthogonal Sub Channels (OSC) in the downlink channel a parameterized, hybrid quaternary modulation is employed. In the hybrid quadrature modulation, the symbol constellation is in quadrature, with the 4 symbols lying on the unit circle in the complex plane. The orthogonality of the 1 and Q branches is preserved. A cross power branch ratio parameter α is introduced, allowing the total energy of the signal to be divided unequally between the two sub channels. This parameter α may be changed from over time.
