The wireless transmitter of claim 1, further comprising a plurality of error-correcting coders encoding respective types of said data before said data are multiplexed by said multiplexer. 4. The wireless transmitter of claim 3, wherein said error-correcting coders employ different error-correcting codes, depending on the quality requirements of said different types of data. 5. The wireless transmitter of claim 1, wherein said wireless channel is a code channel in a code division multiple access system. 6. A method of transmitting at least two different types of data, with different quality requirements, from a first station to a second station in a wireless communication system, comprising the steps of: separately interleaving each of said types of data by writing lines of said data into a matrix memory in a first direction, then reading lines of said data from said matrix memory in a second direction orthogonal to said first direction; multiplexing said different types of data into frames, each frame being divided into a plurality of slots, by placing, for each of said plurality of different types of data, at least one line of data read in said second direction in each said slot; transmitting each said frame on a single wireless channel from said first station to said second station; and controlling transmitting power of each of said types of data separately within each said frame, according to the quality requirements of said types of data. 7. The method of claim 6, wherein each said slot receives just one line of data of each of said plurality of types. 8. The method of claim 6, further comprising the step of coding said data, by an error-correcting code, before said step of multiplexing. 9. The method of claim 8, wherein said step of coding employs different error-correcting codes, depending on the quality requirements of said different types of data. 10. The method of claim 6, wherein said wireless channel is a code channel in a code division multiple access system. 11. The wireless transmitter of claim 1, wherein each of said plurality of interleavers interleaves only one type of said at least two types of data.
