Abstract:
A high throughput communication apparatus which provides low frame error rates (FER). Error checking encoder and decoders which each comprise a plurality of short blocklength error checking encoders or decoders, respectively, in parallel, coupled through common incremental redundancy. Short-blocklength codes are utilized to achieve communication capacity with incremental redundancy. The system can transmit and decode a large number of short-blocklength codewords in parallel, while it delivers incremental redundancy, without feedback, only to the decoders that need incremental redundancy.

Claim (Index 1):
A transmitter apparatus in a communications system, said transmitter apparatus comprising:\n (a) one or more variable-length encoders for a variable-length code configured to take as input a k-bit message and to produce as output an initial transmission sequence of length  1  symbols and a set of m\u22121 increments, where m is an integer greater than one, all increments having the same length  \u0394 , such that if said initial transmission sequence and said increments were transmitted based on non-active ACK/NACK feedback, said variable-length code would approach capacity by exceeding a specified percentage of Shannon capacity of a specified point-to-point channel; (b) an incremental redundancy encoder configured to combine the increments produced by said one or more variable-length encoders to produce a common pool of incremental redundancy to be made available for all variable-length codes at a receiver; (c) wherein said one or more variable-length encoders are configured to produce said initial transmission sequence for a plurality L of said k-bit messages, which are transmitted to a receiver over a channel between said transmitter and said receiver; (d) wherein said transmitter apparatus is configured to additionally transmit to the receiver over said channel between said transmitter and the receiver a number of transmitted symbols less than L\u00d7(m\u22121)\u00d7 \u0394 , corresponding to a common pool of incremental redundancy for the plurality L of said k-bit messages; (e) wherein said number of transmitted symbols corresponding to the common pool of redundancy approximates a number of symbols of incremental redundancy that would have been sent by L independently operating variable-length encoders if said increments were transmitted based on non-active ACK/NACK feedback on said specified point-to-point channel; (f) wherein said transmitter apparatus is configured to have a rate approaching the rate achieved by the capacity-approaching variable-length code when utilized with non-active ACK/NACK feedback; and (g) wherein probability of either failing to decode a k-bit message, or decoding a k-bit message in error is below a target value; and\u2014 (h) wherein k is a number of bits in a message that is encoded by a variable length encoder,  is a length in symbols of a transmission, m is a number of stages including an initial transmission and m\u22121 additional stages of incremental redundancy, and L is a number of short-blocklength codewords.
