Abstract

A transmitter/receiver system for high data transfer in a wireless communication system includes a physical layer processor that comprises an FEC coder, a demultiplexer and a plurality of modem processors. The FEC coder applies error correction codes to the high data rate signal. Thereafter, the demultiplexer distributes portions of the coded high data rate signal to the modem processors. Each modem processor processes its respective portion of the coded signal for transmission in an independent channel.

Claims

1. A transmitter comprising:

circuitry configured to produce by a link layer a single information stream;

the circuitry is further configured to turbo code blocks of the single information stream;

the circuitry is further configured to demultiplex the turbo coded blocks of the single information stream into a plurality of channels;

the circuitry is further configured to process the plurality of channels to produce a respective plurality of code division multiple access (CDMA) channels; and

the circuitry is further configured to combine the plurality of CDMA channels and transmit the combined plurality of channels using at least one antenna.

2. The transmitter of claim 1 wherein the single information stream is a high data rate information stream.

3. The transmitter of claim 1 wherein the turbo code blocks are of a predetermined size.

4. The transmitter of claim 1 wherein the turbo coding of the blocks is performed by one of a pool of forward error correction (FEC) coders.

5. A method for use by a transmitter, the method comprising:

producing by a link layer a single information stream;

turbo coding blocks of the single information stream;

demultiplexing the turbo coded blocks of the single information stream into a plurality of channels;

processing the plurality of channels to produce a respective plurality of code division multiple access (CDMA) channels;

combining the plurality of CDMA channels; and

transmitting the combined plurality of CDMA channels.

6. The method of claim 5 wherein the single information stream is a high data rate information stream.

7. The method of claim 5 wherein the turbo code blocks are of a predetermined size.

8. The method of claim 5 wherein the turbo coding of the blocks is performed by one of a pool of forward error correction (FEC) coders.
