Abstract: The invention relates to a method for storing code symbols and additional control information in a processing means of an encoder of a communication system. In particular, the invention relates to the storing of code symbols together with additional control information in an interleaving memory (IM) of an interleaver. According to the invention, a combining means (COM) combines respective data bits (I, Q) forming a respective code symbol with their associated control bits into a control information/code symbol data word of a predetermined number (K) of bits. A control information/code symbol encoding means (CI/CS-ENC) encodes the control information/code symbol data words into encoded data words of a smaller number of bits. This data word with a smaller number of bits is then stored at a particular memory location in the interleaving memory (IM).

Abstract: The invention relates to a time-alignment apparatus and a time-alignment method of a transmitter (TX) of a telecommunication system TELE. Successive data frames (ch1/0, ch2/0, ch3/0, ch4/0, ch8/0, ch300/0) are written to one or two frame memories (RAM1, RAM2) starting at a respective frame start write address (FRST-ADRchy). A third frame memory (RAM3) having a read state is read out in the column direction such that one data symbol of each storage resource (RES1, RES2 . . . RES300) can be output to a modulator unit (BBTX) of the transmitter (TX). The read/write state (WR/RD) of the three frame memories (RAM1, RAM2, RAM3) is cyclically switched through a first to third alignment mode (M1, M2, M3) such that always a first write state memory (RAM1) and a second write state memory (RAM2) are provided. An interleaving process can be carried out together with the time-offset adjustment if the storage resource is constituted by an interleaving matrix.

Abstract: In a telecommunication system where a plurality of user channels are processed in a time-slotted manner, a transmitter and receiver can perform bit error rate measurements for a plurality of user channels by only using one PN-generator (T-PN) and one state memory (ISM). Whenever the beginning of a new time-slot is detected, a last-stored phase state is read out from the state memory (ISM). When detecting the end of the respective time-slot, the phase state then present in the PN-generator (T-PN) is stored into the state memory (ISM) to be used for re-initialization of the PN-generator (T-PN) for the same time-slot in a succeeding frame. Thus, one PN-generator (T-PN) is enough for generating PN-sequences for a great number of user channels.
