摘要： In a first step, slot synchronization may be obtained by setting in correlation the received signal with a primary sequence, which represents the primary channel, and storing the received signal. During a second step, the correlator may be re-used for correlating the received signal with a secondary sequence corresponding to the secondary synchronization codes. The correlator may include a first filter and a second filter connected in series, which receive a first secondary sequence and a second secondary sequence, which may include Golay sequences. Architectures of parallel and serial types, as well as architectures designed for reusing further circuit parts are also disclosed. The invention is particularly applicable in mobile communication systems based upon standards such as UMTS, CDMA2000, IS95, and WBCDMA.

摘要： A method for decoding signals with encoded symbols over a symbol interval that modulate a carrier. The method includes phase locking the signal to be decoded to obtain a phase-locked signal. The value assumed by the phase-locked signal on at least one subinterval in each symbol interval is detected. The method continues with attributing to the decoded symbol corresponding to each symbol interval a value that is a function of the value detected the subinterval. The subinterval in question can be a single subinterval located at the end of the symbol interval. Alternatively, the value assumed by the phase-locked signal on a plurality of subintervals in each symbol interval is detected, and a respective majority value of said phase-locked signal within said plurality of subintervals is identified. A value determined on the basis of the majority value is attributed to the decoded symbol corresponding to each symbol interval.

摘要： Once slot synchronization has been obtained in a first step, during a second step there is acquired, by means of correlation of the received signal (r) with the synchronization codes, the information corresponding to the codegroup and to the fine slot synchronization. The synchronization codes are split into codesets. In a first step, a synchronization code identifying a corresponding codeset (CS) is identified by means of correlation and search for the maximum value of correlation energy. In a second step, the received signal (r) is correlated with the remaining codes belonging to the codeset identified. The information thus obtained, which corresponds to all the synchronization codes comprised in the codeset identified, is used for obtaining frame synchronization and codegroup identification. Preferential application is in mobile communication systems based upon standards, such as UMTS, CDMA2000, IS95 or WBCDMA.

摘要： To execute the cell-search procedure in a cellular communication system (such as a system based upon the 3GPP TDD standard), there are available identification codes for the second step (slot synchronization) and for the third step (identification of the scrambling codes). The identification codes are identified by a process of correlation with the received signal and are used for obtaining from a correspondence table the parameters for the execution of the second step (CD) or of the third step (SCR). The correspondence table is stored in a reduced form by the identification, according to rules of symmetry and redundancy, of subtables designed to generate the entire table by appropriate combination operations. The search procedure in the correspondence table thus reduced is conveniently modified by the introduction of the combination operations. A preferential application is in mobile communication systems based upon standards such as UMTS, CDMA2000, IS95 or WBCDMA.

摘要： Encoded digital symbols are transmitted via a first pair of antennas and at least one second pair of antennas. The sets of symbols used for the transmission via the second pair of antennas are re-ordered temporally into subsets of symbols with respect to the symbols used for the first pair of antennas. For the first pair of antennas, there is used a signal subjected to encoding with a code-division-multiple-access code and subjected to spreading with a spreading code, and, likewise, for the second pair or pairs of antennas there are used signals subjected to encoding with respective code-division-multiple-access code and subjected to spreading with a respective spreading code. At least one between the respective code-division-multiple-access code and the respective spreading code used for the transmission via the second pair of antennas is different from the code-division-multiple-access code and from the spreading code used for the transmission via the first pair of antennas. The solution can be extended to the use of a plurality of second pairs of antennas in transmission and/or to the use of a plurality of antennas in reception.
