Method and system for utilizing space-time and space-frequency codes for multi-input multi-output frequency selective fading channels

An apparatus for encoding signals for transmission over a communication channel of a communication system, the apparatus comprising:

• a source configured to output a message signal;
• and
• an encoder configured to generate code word in response to the message signal for transmission over the communication channel via a plurality of transmit antennas, the code word having a construction that defines a plurality of paths associated with an intersymbol interference (ISI) environment of the communication channel, the code word achieving a diversity based upon the number of transmit antennas and the number of ISI paths.

• and
• means for generating a code word in response to the message signal for transmission over the communication channel via a plurality of transmit antennas, the code word having a construction that defines a plurality of paths associated with an intersymbol interference (ISI) environment of the communication channel, the code word achieving a diversity based upon the number of transmit antennas and the number of ISI paths.

A waveform signal for transmission over a communication channel of a communication system, the waveform signal comprising:

• a code word that is based upon a message signal, the code word being generated for transmission over the communication channel via a plurality of transmit antennas, wherein the code word has a construction that defines a plurality of paths associated with an intersymbol interference (ISI) environment of the communication channel, the code word achieving a diversity based upon the number of transmit antennas and the number of ISI paths.

A computer-readable medium carrying one or more sequences of one or more instructions for transmitting encoded signals over a communication channel of a communication system, the one or more sequences of one or more instructions including instructions which, when executed by one or more processors, cause the one or more processors to perform the steps of:

• receiving a message signal;
• and
• generating a code word in response to the message signal for transmission over the communication channel via a plurality of transmit antennas, the code word having a construction that defines a plurality of paths associated with an intersymbol interference (ISI) environment of the communication channel, the code word achieving a diversity based upon the number of transmit antennas and the number of ISI paths.
