<p>PURPOSE: To freely select and set information quantity to be transmitted and a data rate at every frame. CONSTITUTION: A channel parameter at every channels less than channels decided by orthogonal coding is set by a frame generating part 2, and frame data is generated from serial transmission data, and a code division multiplex part 3 generates a symbol by performing the convolution coding and punctured coding of the frame data at every channel based on the channel parameter. The orthogonal coding is performed by multiplying an orthogonal code allocated to each channel, and a code division multiplex signal is generated by adding all the output of each channel of one frame, and the code division multiplex signal is multiplied by a PN system from a PN generator 4 by a multiplier 5, and data with data rate varied at every frame is transmitted from a transmission antenna 9.</p> |
