Abstract: The present invention concerns antigen binding proteins directed against PRAME protein-derived antigens. The invention in particular provides antigen binding proteins which are specific for the tumor expressed antigen PRAME, wherein the tumor antigen comprises or consists of SEQ ID NO: 50 and is in a complex with a major histocompatibility complex (MHC) protein. The antigen binding proteins of the invention contain, in particular, the complementary determining regions (CDRs) of novel engineered T cell receptors (TCRs) that specifically bind to said PRAME peptide. The antigen binding proteins of the invention are for use in the diagnosis, treatment and prevention of PRAME expressing cancerous diseases. Further provided are nucleic acids encoding the antigen binding proteins of the invention, vectors comprising said nucleic acids, recombinant cells expressing the antigen binding proteins and pharmaceutical compositions comprising the antigen binding proteins of the invention.

Abstract: The present invention relates to a method of influencing an input signal (x), in particular an input signal of a power amplifier of a wireless communication system, wherein said input signal (x) has a range of input amplitudes (r0, . . . , rM?1), wherein a correction signal (?(x)) depending on said input signal (x) is generated, and wherein said input signal (x) is influenced depending on said correction signal (?(x)). A generation of said correction signal (?(x)) is based on a plurality of base functions (?1, ?2, . . . , ?N?1), and said range of input amplitudes (r0, . . . , rM?1) is divided into intervals (r0,r1),(r1,r2), . . . ,(rM?2,rM?1), wherein each of said base functions (?1, ?2, . . . , ?N?1) contributes to said correction signal (?(x)) in a limited number of intervals ((r0,r1),(r1,r2), . . . ,(rM?2,rM?1)). Thus it is possible to change parts of the correction signal by adapting some of said base functions without influencing the whole correction signal.

Abstract: A synchronization procedure for a multipoint-to-point CDMA network (2), which minimizes the influence on the information transmission. Instead of interleaving communications and synchronization signals timewise, a simultaneous emission is proposed, in which the synchronization signals are superimposed on the communications signals. The synchronization signals are coded with a special synchronization code (6), which does not correspond to the CDMA communications code of the information signals, e.g Barker code. In addition, the synchronization signals are sent at a lower amplitude compared with the communications signals. The synchronization signals are also modulated (7) prior to sending, in particular using alternating multiplication by +1 and ?1. On the receiving side (3), the synchronization signals are detected by demodulation (12; 15), correlation (13; 16) and subsequent accumulation.

Abstract: It is the object of the invention to make available a method of transferring user data packets from a terminal to a mainframe of an S-CDMA point-to-multipoint system, in which the data transfer is optimized. The method includes the steps of a repeated transmission of reference data packets coded with pilot codes for the duration of the connections between terminals and a mainframe, wherein the reference data packets contain previously known information, and the transmission of user data packets coded with communication codes include the user information to be transferred. In a preferred embodiment of the invention the user data packets are coded synchronously in time to the reference data packets, superimposed on these, and then modulated. Each terminal is allocated a pilot code, and at least one communication code.
