Coding assisting equipment, decoding assisting equipment, radio transmitter, and radio receiver
First Claim
1. A coding assisting equipments comprising:
- operating-object means for sequentially holding each word respectively consisting of plural bits of transmission information, and divided into constant word lengths;
argument holding means for holding an argument that should be applied to an operation that is performed on a word that is subsequently held by said operating-object holding means, and the argument being included in said word being held by said operating-object holding means and/or the result of an operation performed in advance on the word being held by said operating-object holding means; and
operation means for performing, as said operation, in accordance with logical values of individual bits that are included in said word being held by said operating-object holding means and said argument being held by said argument holding means, coding that is defined as a logical operation to be performed on a combination of said logical values, and for outputting a word whose word length is constant.

Abstract
A coding assisting equipment is provided in which transmission information is fed in such a manner as to be divided into words having a predetermined word length and is coded collectively through a computing unit that is formed as a combinational circuit. A decoding assisting equipment is provided in which a received sequence is fed in such a manner as to be divided into words having a predetermined word length and is decoded collectively through a computing unit that is formed as a combinational circuit. A radio transmitter and a radio receiver are provided that incorporates the above coding assisting equipment and the decoding assisting equipment, respectively. In a transmission system to which the invention is applied, the service quality and the transmission efficiency are increased in an inexpensive manner, resources are utilized effectively, and flexible application of a variety of systems is enabled.

16. A radio receiver comprising:
-
wireless interfacing means for determining a radio-frequency signal reached through a radio transmission channel, and for dividing transmission information that is given as said radio-frequency signal into words each consisting of plural bits and of a constant word length and for outputting the words;
operating-object holding means for sequentially holding said words that are output from said wireless interfacing means;
argument holding means for holding an argument that should be applied to an operation that is performed on a word that is subsequently held by said operating-object holding means, and the argument being included in said word being held by said operating-object holding means and/or the result of an operation performed in advance on the word being held by said operating-object holding means; and
operation means for performing, as said operation, in accordance with logical values of individual bits that are included in said word being held by said operating-object holding means and said argument being held by said argument holding means, coding that is defined as a logical operation to be performed on a combination of said logical values, and for outputting a word whose word length is constant.
