201 METHOD AND SYSTEM TO SUPPLY DATA TO THE USERS OF A DECT SYSTEM EP97938823.8 1997-07-14 EP0916197B1 2002-03-20 ROSINA, Giancarlo; SALTINI, Giorgio; DE CAMILLI, Giuseppe; PROSERPIO, Vittorio
Method for data transmission in a DECT system including at least one central unit (RFP) and at least one peripheral unit (PP), where the transmission of data between said units is organized in frames having pre-set duration in which a given number of time slots are allocated. The method foresees the low speed data transmission enabling only the field S and the field A of each time slot, disabling at the same time the field B provided for the transmission of data according to the conventional DECT standard. Disabling the above mentioned field B, it is possible to reduce by 70 % (seventy percent) approximately the power required to implement data transmission operations. Therefore, said method is particularly advantageous in whichever "data exchange/data collection" application foreseeing the use of the DECT standard and requiring fixed or mobile low power consumption peripheral stations with local battery supply.

203 Control channel for time division multiple access systems EP00303906.2 2000-05-09 EP1067714A1 2001-01-10 Krishnamoorthy, Rajeev; Rupp, Markus; Viswanathan, Harish

In a TDMA system a multifunction control channel is employed that carries data used for implementing channel access functionality for users and is also employed at the remote terminals in the performance of modem functionality. In other words, information necessary to accurately receive data on the user traffic channels is obtainable by processing the multifunction control channel. This is achieved by arranging the broadband channel of the TDMA system as a repeating frame having time slots in which at least one time slot is reserved for use as the multifunction control channel, and the data that is transmitted on the multifunction control channel is encoded using a spread spectrum format. To this end the data carried on the multifunction control channel is encoded in a way that uses each symbol of the multifunction control channel as if it were a so-called spread spectrum "chip". At least one of the remaining time slots of the frame, and preferably all of the remaining time slots, which are typically used to carry user traffic arranged as logical channels, are not spread spectrum encoded. With regard to modem functionality, the remote terminals use the received multifunction control channel to a) perform frame synchronization, i.e., frame timing, b) perform frequency offset estimation, c) obtain an estimate of the channel impulse response, and d) estimate the received signal strength for use in gain control.

To detect the number of transmit antennas, a fast Fourier transform operation is performed on the received samples of the transmitted long training symbols of a preamble. Next, each of the Fourier transformed results is multiplied with the reference frequency-domain representation of the long training symbol so as to remove the effect of the symbols and to maintain the channel information. Next, inverse Fourier transform or least squares operations is performed on the multiplied values to compute channel impulse response. The number of shifted impulse response in the channel impulse response represents the detected number of transmit antennas. Packets containing preambles of the present invention may be received by extended devices as well as by legacy receivers that are not configured to receive and interpret these preambles. The training symbols may be cyclically-shifted and transmitted on different transmit antennas.
