SYSTEM FOR TRANSMITTING DATA BETWEEN BOARDS

摘要

PURPOSE: A system for transmitting data between boards is provided to decrease the number of pins for transmitting data between boards by transmitting a hot link transmitting and receiving apparatus when data are transmitted between boards. CONSTITUTION: First to nth modulating and demodulating units(21a-21n) transmit a plurality of generated signals using transmission lines having the 1/2 number of generated signals. A plurality of multi-channel processing units(20a-20n) have first to nth hot link transmitting units(22a-22n) for receiving signals transmitted from first to nth modulating and demodulating units(21a-21n). First to nth hot link receiving units(23a-23n) receives a plurality of signals transmitted from first to nth hot link transmitting units(22a-22n). A combining unit(25) combines signals received in first to nth hot link receiving units(23a-23n). A base station upward/downward sector processing unit(28) has a hot link receiving unit(28a) for receiving a signal transmitted from a wireless channel processing unit(27).
