Adaptive coding and modulation

A method for adaptive coding and modulation, the method comprising:

• generating, utilizing one or more processors, a set of mapping functions based on a set of communication channels;
• and
• transmitting a tth set of transmit symbols in a tth time interval by transmitting an (i, t)th transmit symbol in the tth set of transmit symbols by an ith transmitter in a set of transmitters where 1≤i≤N, N is a size of the set of transmitters, 1≤t≤T, and T is a maximum number of symbol transmissions, transmitting the (i, t)th transmit symbol comprising:
• generating an (i, t)th set of mapped symbols by applying an ith mapping functions subset of the set of mapping functions on one of an ith data vector and a set of channel state information (CSI) samples of an ith channels subset of the set of communication channels in the tth time interval, wherein:
• each mapped symbol in the (i, t)th set of mapped symbols comprises a respective complex value;
• each mapping function in the ith mapping functions subset depends on a respective mapped symbol in an (i, r)th set of mapped symbols where 0≤r≤T;
• and
• each mapped symbol in an (i, 0)th set of mapped symbols is zero;
• generating the (i, t)th transmit symbol from the (i, t)th set of mapped symbols;
• and
• transmitting the (i, t)th transmit symbol through the ith channels subset.

A system for adaptive coding and modulation, the system comprising:

• a set of transmitters;
• a memory having processor-readable instructions stored therein;
• and
• one or more processors configured to access the memory and execute the processor-readable instructions, which, when executed by the one or more processors configures the one or more processors to perform a method, the method comprising:
• generating a set of mapping functions based on a set of communication channels;
• transmitting a tth set of transmit symbols in a tth time interval by transmitting an (i, t)th transmit symbol in the tth set of transmit symbols by an ith transmitter in the set of transmitters where 1≤i≤N, N is a size of the set of transmitters, 1≤t≤T, and T is a maximum number of symbol transmissions, transmitting the (i, t)th transmit symbol comprising:
• generating an (i, t)th set of mapped symbols by applying an ith mapping functions subset of the set of mapping functions on one of an ith data vector and a set of CSI samples of an ith channels subset of the set of communication channels in the tth time interval, wherein:
• each mapped symbol in the (i, t)th set of mapped symbols comprises a respective complex value;
• each mapping function in the ith mapping functions subset depends on a respective mapped symbol in an (i, r)th set of mapped symbols where 0≤r≤T;
• and
• each mapped symbol in an (i, 0)th set of mapped symbols is zero;
• generating the (i, t)th transmit symbol from the (i, t)th set of mapped symbols;
• and
• transmitting the (i, t)th transmit symbol through the ith channels sub set.
