Abstract

Provided is a generalized Recursive STTC (Space-Time Trellis Code) encoder which can improve diversity gain and coding gain in terms of transmission without increasing circuit complexity in a transmission system by forming an internal encoder of a multi-antenna mobile telecommunication system using a Recursive Systematic Convolutional code (RSC) block having two output ends to form a systematic ineral encoder. In addition, the generalized RSTTC encoder has a ratio of input data to output data (n−1):n by using a plurality of parallel RSC blocks each having two output ends. Thus, flexibility can be given to the size of data input to each RSC block and a transmission data rate can be improved in the internal encoder of a transmission system.

Dependent claims

A generalized Recursive Space-Time Trellis Code (RSTTC) encoder in a multi-antenna mobile telecommunication system using a Space-Time Trellis Code (STTC), the generalized RSTFC encoder comprising:

a serial-to-parallel converter for receiving and parallel-converting a data bit (a);
a second predetermined number (K) of Recursive Systematic Convolutional code (RSC) blocks for receiving data of a first predetermined number of bits (nk−1 bits) among parallel-converted data bits (m bits) output from the serial-to-parallel converter and outputting the received data of the first predetermined number of bits and data resulting from processing of the received data of the first predetermined number of bits;
and
a mapping distributor for receiving data output from the second predetermined number of RSC blocks, mapping the data to multiple antennas, and transmitting the data to the multiple antennas.
