Abstract: PURPOSE: An apparatus is provided to transmit and receive frame messages having different frame lengths from each other, and to intermix frame messages having different frame lengths from each other to transmit the intermixed result. CONSTITUTION: A message buffer(511) stores a frame message communicated when communicating a frame message via a dedicated channel. A modem controller(513) reads the frame message stored in the message buffer(511), parses a message type from a header of the read message, outputs data of a frame to be transmitted via the dedicated channel according to a message type of the parsed frame, and outputs a frame select signal according to the message type of the parsed frame. The first message generator(550) includes a cyclic redundancy check(CRC) generator(515), a tail bit generator(517), a coder(519), and an interleaver(521), and receives the first frame data from the modem controller(513) to generate the first frame message. The second message generator(560) includes a CRC generator(516), a tail bit generator(518), a coder(520), and an interleaver(522), and receives the second frame data from the modem controller(513) to generate the second frame message. A multiplexer(523) receives outputs of the first and second interleavers(521, 522) and selects any one of the received inputs in response to the frame select signal(SCTL) from the modem controller. A signal converting part(522) converts the frame message from the multiplexer to output the converted values to the first channel and the second channel. Gain controllers(527, 528) receive signals from the control bit inserting part(531) to control a gain of received signals in response to a gain control signal(GCTL) from the controller(513). An orthogonal code modulator(533) generates an orthogonal code in response to orthogonal code number and length of an assigned channel. An extension modulator(535) mixes the orthogonal modulated signal with an extension sequence.

Abstract: PURPOSE: An apparatus for controlling a continuous outer power control loop is provided to control the outer power control loop regardless of data, by tabling frame error rates for signal-to-noise(SN) ratios, and by referring to the tabled frame error rates to decide whether frames have errors when the data is not transmitted in a discontinuous transmission mode of a code division multiple access(CDMA) communication system. CONSTITUTION: An apparatus for controlling a continuous outer power control loop comprises a cyclic redundancy check(CRC) error detector(925), a frame detector(924), a signal-to-noise ratio calculator(919), a data detector(927), and a frame error detector(929). If a frame is received, the CRC error detector checks an error of the frame to output a checked result. The frame detector measures energy of the frame to output the frame. The signal-to-noise ratio calculator calculates signal-to-noise ratios to output the ratios. The data detector receives the checked result and the frame energy to generate an existing frame flag message. The flag message presents whether a frame exists or not. If a frame received by the flag message exists, the frame error detector outputs the checked result to the outer power control loop. If the frame does not exist, the frame error detector estimates a frame error by the signal-to-noise ratios.
