Abstract: A phase recovery and decoding method for decoding signals (S'(t)) comprising encoded symbols (u k ) over a respective symbol interval (T) which modulate a carrier, for example in a TCM system. The method envisages performing (20 to 26) a phase locking of the signal to be decoded so as to obtain a phase-locked signal which can present, during each symbol interval (T), variations induced by disturbances (noise, fading, etc.). The value attributed to the decoded symbol (U k ) is a function of the value assumed by the phase-locked signal on at least one subinterval of the symbol interval (T), for example located at the end of the symbol interval (T). Alternatively, the value assumed by the phase-locked signal on a plurality of subintervals comprised in each symbol interval (T) is detected (24,32), and a respective majority value of said phase-locked signal within said plurality of subintervals is identified (34,36). A suitable phase recovery and decoding circuit comprises a phase comparator (20), hard decision means (24), an encoder circuit (26), an oscillator (22) and a selection unit (28). For determining decoded value (U k ) and updating the state of the encoder circuit.

Abstract: In a first step, slot synchronization is obtained by setting in correlation (210, 220) the received signal (r) with a primary sequence (SG), which represents the primary channel (PSC), and by storing said received signal. During a second step, the said correlator (210, 220) is re-used for correlating the received signal (r) with a secondary sequence (SSC) corresponding to the secondary synchronization codes. The correlator (210) is preferably structured in the form of a first filter (210) and of a second filter (220) set in series, which receive a first secondary sequence (SG1) and a second secondary sequence (SG2), typically consisting of Golay sequences. Proposed herein are architectures of a parallel and serial type, as well as architectures designed for re-using further circuit parts. A preferential application is in mobile communication systems based upon standards such as UMTS, CDMA2000, IS95, or WBCDMA.

Abstract: Encoded digital symbols (S 1 S 2 S 3 S 4 ) are transmitted via a first pair of antennas (Tx1, Tx2) and at least one second pair of antennas (Tx3, Tx4). The sets of symbols used for the transmission via the second pair of antennas (Tx3, Tx4) are re-ordered temporally (S 3 S 4 S 1 S 2 ) into subsets of symbols with respect to the symbols used for the first pair of antennas (Tx1, Tx2). For the first pair of antennas (Tx1, Tx2) there is used a signal subjected to encoding with a code-division-multiple-access code (CDMA) and subjected to spreading with a spreading code (c 1 ), and, likewise, for the second pair or pairs of antennas (Tx3, Tx4) there are used signals subjected to encoding with respective code-division-multiple-access code (CDMA) and subjected to spreading with a respective spreading code (c 2 ). At least one between the respective code-division-multiple-access code (CDMA) and the respective spreading code (c 2 ) used for the transmission via the second pair of antennas (Tx3, Tx4) is different from the code-division-multiple-access code (CDMA) and from the spreading code (c 1 ) used for the transmission via the first pair of antennas (Tx1, Tx2). 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.
