Abstract: THE PRESENT INVENTION DISCLOSES A METHOD FOR ESTIMATING THE RECEIVED SIGNAL STRENGTH INDICATOR (RSSI) AND THE CARRIER-TO-INTERFERENCE PLUS NOISE RATIO (CINR) OF A SERVING BASE STATION (BS) AT A MOBILE STATION (MS) IN OFDMA/OFDM-BASED COMMUNICATION SYSTEMS. THE STEPS OF ESTIMATION ARE NOT DEPENDENT ON THE NUMBER OF INTERFERING BASE STATIONS (BSS), THEIR CELL IDENTIFICATIONS (ID), ASSOCIATED PREAMBLE SEQUENCES OR THE CSI. FIG 2

Abstract: A method of producing signals to emulate TETRA direct mode physical layer to a broadband network, particularly WiMAX network is disclosed. Frames of broadband signals are arranged as a time slot to form a direct mode multiframe, said multiframe is made up of 18 direct mode frames according to TETRA direct mode specification. Two time slots are provided for a call transaction, a first and third time slot within a direct mode frame, for every communication channel. A proper modulation is later assigned for each direct mode burst including linearization burst, synchronization burst and normal burst. The preamble of direct mode burst shall be different from the one used for WiMAX.
