Title: Decoder for superimposed code
Inventor: IWAKIRI NAOHIKO
IPC: H03M13/00
Filed: 1988-05-16
Abstract: PURPOSE:To obtain a decoder with a high error correction capability by selecting a code based on the result of parity check as one factor. CONSTITUTION:An error control code FL (n, k, d) of n-bit in code length and (d) in inter-code distance is constituted as to the initial k-bit corresponding to an input signal in information length k+k' bits/and an error control code FO (n, k', d') of n-bit in code length and d' in inter-code distance is constituted as to the remaining k'-bit, then a superimposed code including LH being exclusive OR of each bit of FL, FO and RH being FR of the same signal as the FL is decoded. In this case, any code is selected by using the result of parity check of RH' being the result of receiving RH being the addition of a parity bit to the code FR as one factor. Thus, a decoder with a high error correction capability is obtained.

Title: Call transmission control method
Inventor: MURAI MASAO
IPC: H04B7/26
Filed: 1992-05-12
Abstract: PURPOSE:To reduce the congestion state in a radio zone with a simple method by adding pseudo channel information representing call transmission by a mobile station but not establishing a call to transmission channel information. CONSTITUTION:A pseudo channel is included into information of an outgoing control radio signal L4 in response to the operating state of an outgoing control channel controlled by a control station 1 such as a fault recovery or the like at a base station 4. A mobile station 5 acquires the pseudo channel of the signal L4 and makes transmission through the channel but the control is not in progress. Thus, the mobile station 5 after a prescribed time acquires the information content in the signal L4 again and makes transmission. For that time the probability of simultaneous calls from plural mobile stations 5 is reduced and collision of an incoming call control radio signal L3 is avoided. Thus, the congestion state is simply reduced.
